I’m enjoying Zen browser in general but still facing several issues with it from time to time. Nothing major, just small nuisanses here and there.

I use it alongside Vivaldi since I often have to be logged in into two different sessions for the same site and it’s just easier to have two browsers for that. Vivaldi is a lot more stable and so I use it as the main browser - but everytime it updates I need to modify a JS file to tweak something in the UI to make it the way I like it to be. When using vertical tabs + tab groups + two layers of tabs (one sidebar showing the tab groups and a second sidebar showing the tabs inside the selected group), the maximum tab width is applied to both sidebars together instead of individually, so I modify the JS file to double that max width. I’ve automated it by now but it still annoys me that I keep having to do this.

But I think Vivaldi is probably the only browser that even has the ability to show tabs in that way, so I can’t complain that much.
