• (2022-08-16) Den Solodenko: Doesn't work; it showed up once, and never again.
• (2020-11-11) Brent Barrand: I like to use it for my spam folder to keep track of possible false positives. The only problem is that if I started in another folder, I currently have to reload the page to get it to show up in the spam folder. I would give this five stars if, I did not have to do that every time I want to switch to a new folder and still be able to use this button.
• (2020-09-15) //: In Google Chrome and MS Edge, the button only appears on the 'Inbox' page. Clicking other Gmail menu labels, the button only appears when I reload the page. So clicking 'More' and then 'Mark all as read' is just as many clicks. Pitty it doesn't work as advertised.
• (2020-01-23) Chris Hanson (Xenon): I really wish this had worked. It does work, when it appears, but the button disappears constantly. Have to uninstall and look for a different solution.

• (2017-09-07) Daniel Murray: Good idea but buggy and needs improvement. Often doesn't even show up and you need to re-load the page. Would also be great if it done "mark as unread" and also I'd like to be able to just mark ALL visible messages in my search/view as read with needing to select which email emails.

• (2017-05-31) Michael Amico: works for me on all tabs. great little app. NEXTUP: mark read and archive button????
• (2017-01-31) Ralph Lange: For me, it seems to work only for my Inbox, not for any of the other folders.
• (2015-06-10) Jordan Bowness: Was good while it worked, but seems an update to Gmail as rendered it non-functioning?
