I understand that you foxy folks love your extensions and scripts, and I'm wondering if I could be happy amongst you.
In Vivaldi (and previously in Opera), I have used vertical tabs for I think twenty years. As you can see in the screenshot, Vivaldi lets me list the tabs vertically, shows previews for them, lets me group the tabs into "stacks", and lets me tile any number of tabs on the window at once. I don't think I could use a browser without these features.
I also use mouse gestures very heavily, to open tabs, windows, switch between tabs and windows, reload pages, etc. Vivaldi and Opera have really robust mouse gesture support built in.
How close can I get to these features natively or with extensions?
TIA!
