Overview
Product summary
Review the store description, core capabilities, and common use cases.
Gmails buttons are all visually identical, which makes it too easy to hit the wrong one. Frustrated by the number of times I hit the SPAM-button rather than the DELETE-button as intended, I made this light weight Chrome extension to make the buttons easier to distinguish.

The only thing it highlighted was the unsubscribe button in my emails.
Non funziona!! (MacOs Big Sur)
This is not a review, it's a call for help. I installed the extension, but the buttons never showed up on my Gmail page. What am I doing wrong? I rebooted a couple of times, but that's the only trick I know and that didn't work. Can you, Michael, or someone else give me a pointer or two?
Simple yet great! A must-have extension, at least until Google listens to the people telling them to swaps the "Mark as Unread" pull-down menu item with the "Spam" button! (Like they listen to anyone. *eyeroll*)
Would be perfect if it added a space in between the buttons. Maybe 20px or so (or customizable). Already greatly improved the usability though, thanks!
Brilliant, nothing less than brilliant :-)
No more misclicks!
