CRX id


Description from extension meta

Split Screen made easy. Resize the CURRENT tab and tabs to the RIGHT into layouts on separate windows. w/ Multi Monitor Support.

Image from store Tab Resize - split screen layouts
Description from store For a more easily readable description please visit: https://github.com/peterdotjs/tab-resize ***** Version 2.3.0 -------------------------- Added default shortcut keys for: Ctrl + Shift + Z: Undo Last Resize Ctrl + Shift + 1: 1x1 Resize Ctrl + Shift + 2: 1x2 Resize Ctrl + Shift + 4: 2x2 Resize Can still be changed through shortcut key menu. Version 2.2.0 -------------------------- Added support for shortcut keys and scaled split screen layouts. Version 2.1.1 -------------------------- HIGHLIGHTED TABS NOW CAN BE RESIZED (not only tabs to the right) - when 2 or more tabs are highlighted, only these tabs will be considered for resize. In Chrome, you can select multiple tabs by clicking on tabs while holding down the Ctrl (Command for Mac) key or select a range of tabs by holding down the Shift key and clicking. Version 2.1 -------------------------- Added support for multiple monitors, left and right alignment, empty tab mode, drag and drop to rearrange layouts and highlighted tab mode. Fully supports Windows, Mac and Linux OS. ***** @everyone that's liked it, thanks a lot for the support! I'm really glad you guys found it useful. You're pretty much the motivation continuing to build and improve the extension. =) This extension will not resize within the same tab (multiple panes with only ONE url bar). Other Chrome extensions with multiple panes in one tab have security limitations (i.e. you can't see any https site like Gmail or Facebook). With these types of extensions you also won't be able to access any of your favorite extensions on the individual panes. Tab Resize has none of the limitations listed previously because it splits tabs into separate windows. Thanks for checking it out! =) Cheers, Peter Video DEMO ---------------------- http://www.youtube.com/watch?v=GFHl98nAV04 If you like it please rate it and if you have any feature requests, questions or bugs you file it here: https://github.com/peterdotjs/tab-resize/issues?state=open What -------- ✓A simple extension designed to provide ease in resizing your tabs. A set of default layouts are provided but you can add and remove from the list of layouts to fit your needs. With multiple monitor support you can move windows from one screen to the next with ease. ✓Has the functionality of Tab Scissors and much much more! Why ------- ✓Manually resizing windows is no fun. ✓You have a very large monitors and have more pixels than you know what do with. ✓Quick side by side comparisons. How it works ------------------- ✓The selected/highlighted tab along with all tabs to the right of it will be considered. Whether you have more or less tabs than are needed the extension will resize only the available tabs. ✓Undo button will undo the previous layout resize. You can only perform undo once at any time. ✓In 'single tab' mode, only the selected/highlighted tab will considered. Only the current window/tab will change in size, all other tabs to the right will be ignored. ✓In 'empty tab' mode, new windows with empty tabs will be created if there are not enough tabs to fill your selected layout. ✓You can select left or right alignment for your resize ✓You can create your own custom layouts within reason and reset to default configurations if desired. Layouts are sorted most recently created on top right. ✓Click and hold on any layout and drag to rearrange order to your liking ✓Highlighted tabs now can be resized - when 2 or more tabs are highlighted, only these tabs will be considered for resize. Credit goes to F.C. for the idea. In Chrome, you can select multiple tabs by clicking on tabs while holding down the Ctrl (Command for Mac) key or select a range of tabs by holding down the Shift key and clicking. Additional Notes ------------------------ Only tab/window id info is being used; browsing activity is not. Tabs and browsing activity access are bundled together. "tabs" permissions is one of the least invasive permissions that are available. Browsing activity you should note is NOT the same as Browsing History. "Browsing activity" means the current tabs that are open not your previously closed tabs. This permission is required because this extension needs to manipulate and move tabs around (an essential feature of this extension) If you feel uncomfortable with this basic permission please don't install it. Giving it a bad review because you don't understand or like the permissions doesn't do anything productive. All my code is open sourced on github (https://github.com/peterdotjs/tab-resize) so feel free to look at how I'm using this permission. It's good to be informed and understand the permissions of any extension you install. For more chrome permission information go here: https://developer.chrome.com/extensions/declare_permissions Anonymous usage tracking (# clicks on the different resize options) is used to improve the extension and user experience. You can opt out in the options menu.

  • (2023-10-28) A A: Looking for something to split my tab into 2.
  • (2023-10-20) Si Ni: Brilliant extension and the multi screen updates work great on my setup (laptop 14" + 2 x 28" monitors). Used it reliably for years and never had any issues. Great idea well executed, kudos to the Dev.
  • (2023-10-11) Haley Rodriguez: Awesome extension that works exactly as desired. Well done!
  • (2023-10-08) Jay Huang: thankyou
  • (2023-09-15) André Laan: This is a nice tool, but Undo is eating up my Tab groupings :-(
  • (2023-06-15) Aman Verma: Absolutely amazing. Thanks a lot. Works perfectly
  • (2023-06-13) Víðarr Kerr: At least the author explained what this was in a popup before you use it. But, even still, it is misleading; all this does is create a giant mess of open windows that have to be manipulated one at a time, each its own. If you have four tabs open and you want to split in four, you cannot do it. You get 4 tabs in your one, existing window and three new windows with blank tabs. If you go to split two of the new tabs, you get two new tabs and the others are buried. Then, you have to close them All One At A Time. There is also no way to toggle them at once. A GIANT MESS is what you get. Useless.

  • (2023-03-25) Kingsley Foote: Has been working perfectly for months. Stopped Working. does not work anymore :(
  • (2023-03-22) Kaylee Rider: It's obviously going to split into windows and not tabs, y'all. A tab only holds one website, but a window can hold multiple websites. I've been using it for some time now, and I like it. For those of you who don't like it, you could just go use another extension instead of coming on here and complaining about it. That would be the nicer thing to do ya know. Either way, I like it, and if you don't, that's on you.
  • (2023-02-11) Rick Miller: I actually like the extension and would use it but it kills my tab groups.
  • (2023-02-08) Cédric Sütterlin: Funktioniert einwandfrei. Der aktuelle Tab wird mit dem Tab rechts geteilt.
  • (2023-01-09) Yura Inversion: On split it moved all my groups to the second window, and then on Undo — it broke all my groups and returned raw 100 opened tabs to the first window. It was terrible (
  • (2022-12-15) Luiz G. Alonso: Could have option to split the same tab!
  • (2022-11-28) Chris Nordin: Splits windows, not tabs. Should have read the reviews first..
  • (2022-08-30) ชญานนท์ นที: ok ตอบจดมากๆครับ สะดวกขึ้นเยอะ
  • (2022-08-09) In The End: Useful. Perfect.
  • (2022-08-07) Alex: Love this app, but I found a better one which allows me to do do multiple tabs in one window https://www.neonav.co/
  • (2022-07-06) Dragan Filipovic: Terrible approach, Ok, it's stated that it splits windows, not tabs. That was expected. - But once you split into windows there is no going back anymore. - Splitted window will lose all grouped tabs I've lost months of tabs grouping and arrangements. What this extension can do, you can easily do manually without negative sideffects. If extension only affects current and only next tab(s) based on the layout, not all next tabs, then this would make sense.
  • (2022-06-30) Sue Troupe: Now I can watch my favorite YouTube videos while I check my email. I love this extension.
  • (2022-06-01) Samuel Doring: Disappointed to not be able to choose the exact size of a widow for dev testing purpose while it seems that the tool has all the options to do it.
  • (2022-04-17) Samuele gg: Non funziona bene. La finestra corrente si divide correttamente, ma apre automaticamente una nuova finestra per intero senza dividersi. Suggerisco, invece, l'estensione "Split Screen for Google Chrome" che funzione bene. ______________________________________ It does not work well. The current window splits correctly, but automatically opens a whole new window without splitting. Instead, I suggest the "Split Screen for Google Chrome" extension which works well.
  • (2022-04-16) Adem kökay: Her şey çok güzel Allah razı olsun işleri kolaylaştırıyor. fakat bir özellik ekleyebilirsen çok daha güzel olacak. farklı sayfaları ve bunların içindeki sekmeleri de seçebilmek çok güzel olurdu. eline sağlık
  • (2022-04-13) Mike Vinsel: This is the best tab resizer I have tried... I really like that it has an undo command to put all tabs back where they started.
  • (2022-04-07) profcfuller: Not multiple tabs in one window, just opens a new window...we already know Microsoft+left
  • (2022-03-03) Jimin Park: This extension is so useful especially on mac because the automatic multi-window on Mac is quite nonexistent. It's just so easy to split windows and it's a total game changer for how I use Chrome.
  • (2022-02-06) ジード: 使い勝手がよく大変お世話になりました。
  • (2022-01-26) Pat MySecret: 5/8/21 I prefer Tile Tabs WE for its simplicity in splitting screens and more readily identifiable icon, but this extension has other useful features. It's more for someone, likely graphic artists, webpage creators, and presentation makers, who have an unusual need to size tabs to exacting sizes. 1/26/22 Tried again. Nice, but there were little gap spaces, and my extension icons, that I was all ready to use, vanished as long as in use. Anyways, glad I listed my former favorite, ..that's my kickback for doing these reviews.
  • (2022-01-15) Neema Naiaghi: It's good and gets the job done kinda useless tho!
  • (2021-12-03) makoto harada: good split tab! I'd like to need CENTER Align, Please put on♪ Please next Version.
  • (2021-11-11) Pete Mitchell: I'm running three 32" monitors...two horizontal and one vertical. I'm also using Mouse Without Borders ...sharing my mouse and monitors on two computers. This app runs ok for a few minutes...and then crashes my system. I uninstalled, and re-installed three times. Perhaps it doesn't work with my setup. Wish it would work...I really like what it's supposed to do. Unfortunately it doesn't.
  • (2021-10-31) Alicia Garcia: Loving the multiple screens at once!
  • (2021-10-26) very useful to my needs. I like it.
  • (2021-10-20) Seth Bullis: What an excellent and useful extension. This should be built into chrome OS. Having 4 tabs open is now possible on a small Chromebook.
  • (2021-10-04) Reem Alkhaldi: perfect app It's great when working.
  • (2021-09-06) Philippe GODEFROY: Complètement inutile. SI GC est ouvert avec 4 onglets, l'extension n'éclate pas la session en 4 fenêtres avec un onglet par nouvelles instance, mais l'onglet courant avec 4 fenêtres vides. En plus CTRL Shift 4 c'est avec le 4 de l'apostrophe pas celui clavier numérique Complètement nulle cette extension. Du coup je retire C'est dingue comment des gens peuvent perdre bêtement leur temps à faire n'importe quoi. Alors qu'il serai tellement plus pratique et intéressant d'avoir tous les onglet ouverts en une seule page façon vignettes.
  • (2021-08-17) Lester L. Carey: GREAT JOB,,,, PETER. THANK YOU !
  • (2021-08-06) Mat Bee: Doesn't seem to do anything other than open another instance of chrome.
  • (2021-07-17) maleta: Just what I needed!
  • (2021-07-01) Tammi L. Coles: Exactly what I was looking for! Thank you, too, for creating the explanatory video. Makes it very clear how to use it and even gave me ideas for how I might apply it in other cases. Really grand!

    Hi guys i've been using this app for ages and I love it, but today I need to use it and sometime between yesterday and today it no longer works! When I press the extension it just keeps one window - I cannot open a new tab on the other side of the screen (it just moves all my current tabs to the left or right without the option of a new window on the other side). Any ideas?

  • (2020-10-12, v:2.3.3) Tina Childress: Resized windows align too high on the screen
    I have a MacBook Pro (early 2015) and recently, I have noticed that when I use this extension, it will fill the page lengthwise but heightwise, it's a little too tall and I only see the bottom of my tabs. I then have to select my window, bring it down a bit and make the window shorter. This defeats the purpose of this app having to resize manually. I've checked the options and don't see any kind of fix. Help? Thanks.
  • (2020-09-09, v:2.3.3) code lazar: Display
    Can you make it so one screen overlaps the other but it's small? Basically what facetime looks like with two people. I can resize the tabs on Chrome but when I click on the big one it covers the little one. I was wondering if this is possible because I would like to be able to watch something in the corner while I'm doing work on the big tab. Please and thank you! :)
  • (2020-08-26, v:2.3.3) Jonathan Holmes: Is there a way to disable the keyboard shortcuts?
    When I use the extension, I like to click on the extension icon to specify exactly what I want to happen. However, more often, I accidentally trigger one of the keyboard shortcuts, while attempting to execute some other command not related to the extension. This is quite a nuisance. Given I had no desire to use the keyboard shortcuts, I'd like if there were an option to disable these, so they they don't intrude in my work. Many thanks for your work on this!

  • (2020-05-08, v:2.3.3) Salvatore Di Bella: tab resize split screen layouts
    I have a Windows 10 pro operating system, when I activate the resize tab, I get this message:ATTENTION: Please Read Before Using This extension will not resize within the same tab (multiple panes with only ONE url bar). Other Chrome extensions with multiple panes in one tab have security limitations (i.e. you can't see any https site like Gmail or Facebook). With these types of extensions you also won't be able to access any of your favorite extensions on the individual panes. Tab Resize has none of the limitations listed earlier because it splits tabs into separate windows. Apologies if you've read the description or watched the demo already - with many of the past reviews that have been left I hope you understand why I've added this popup.

    On Friday, September 6th I set this up on a computer and it worked great. I have been using it for a long while and it's worked fine. For some reason today, it's not working on the other computer and, as it turned out, mine either. Perhaps there was some kind of update Friday that messed this up? When I click any of my custom 2x3 or 2x4 buttons, it resizes the entire window to the size of 1/6th or 1/8th of my monitor, as though it was sizing and making room for the rest to spread the tabs out, but it never does. The tabs all stay in the first window which was resized.
