  • (2020-03-03) Abdallah Omar: I like it , but can you please: 1. add an ON/OFF BUTTON. The only way to turn this thing off is to remove the extension. 2. Update it to bootstrap 4 . The Extension doesn't show (xl) size.
  • (2019-08-16) S H: its good but you NEED AN ON/OFF BUTTON. The only way to turn this thing off is to remove the extension. Which I am doing now because I simply need to take a screenshot. Super annoying.

  • (2018-07-04, v:0.9.7) Select Lg resizes to Sm
    When I want to scale it to Lg the window scales down to Sm. Same with the other sizes they seem to be to small. lg -> sm md -> sm sm -> xs xs -> xs The indicator at the top right seems to be working and it tells me the correct size when I resize the window by hand. All my screens are 1080.
  • (2017-11-28, v:0.9.6) Valentin D.: Clik area reserved by addon
    Hi There is a problem when trying to click in an area that was previously covered by the size icon. Even though the icon is not there anymore, I cannot click on the close icon because of the plugin wrapper: http://prntscr.com/hg9ahl The only workaround I could find was t disable the plugin when I do not use it.
  • (2017-08-29, v:0.9.6) Monia B.: MD doesn't load
    Hi Jonatan, Thanks for your app. The md loading doesn't launch. But a dupplicate sm loads. Have a nice day!
  • (2017-08-14, v:0.9.6) Loren Dorez, Jr.: Boostrap 4
    It would be nice to have a toggle for BS3 vs B4 as the major difference is the breakpoints. BS3: https://getbootstrap.com/docs/3.3/css/#responsive-utilities BS4: https://v4-alpha.getbootstrap.com/layout/responsive-utilities/
  • (2017-03-20, v:0.9.6) Prasong Aroonruviwat: bh-simple-helper prevent click element under it.
    bh-simple-helper class has z-index 100000 that make it top most element and cannot click element under it. Please add pointer-events: none; to its style to solve this problem.
  • (2016-09-27, v:0.9.6) Cristian Deschamps: Bootstrap 4
    Do you have one working with Bs4 or custom breakpoint?
