Just giving you a hard time. I prefer FOSS generally, but most of my time on a desktop is spent on the web, and Arc’s tab/space management is far ahead of anything else right now. It genuinely makes my life easier. The UX is thoughtfully designed and cohesive; even if I could get close to this setup with Firefox extensions (and I tried), it would be janky (and it was).
I’m very much hoping some of Arc’s UX and workflow ideas will be picked up by browsers generally.
