My suggestion is about to improve the handling with add-on icons. I use many add-ons so the Address panel becoming really short now. I prefer to see all of my add-on icons, but with the combination of fast hide/show. Yes, i know that i can hide selected icons under the Main menu. But in my opinion it will be better to have an extra button directly on the Add-ons bar (before the “three lines button”) where all icons marked to be hidden will be stored. It will be separated from the Menu bar. I would like to mention here the solution from Firefox, and Vivaldi too (this solution there is really nice). In my point of view this solution with an extra hide button is better.
Do you think you can consider this icon button on the Add-on bar?
