my initial, 15min impression is.. wow so much to like here! It feels very snappy, really nice UI, supports "real" version of uBlock Origin, has built-in Vertical Tabs with nesting and Tab Groups, and also the iOS-like grid of tabs if you prefer.

What I don't like: Seems like no way to disable two-finger back/forward gesture? I hate that one and managed to disable a similar feature in Chrome. Also either it doesn't have any kind of Developer Tools, or I couldn't find it yet in my 15min speedrun. (edit: found it)

I'm hopeful.
