looks like arc is changing the ui space quite well

Arc the browser? The idea of vertical tabs is way older. Firefox has had Tree Style Tabs or variants for a long time, for example.

UniPress Emacs for NeWS, with tabbed windows and pie menus: 1988.

I think Arc is the first browser I’ve seen to not offer it as a toggle, but instead make it the default and only option and to design the rest of the UI around it. Wouldn’t be surprised if for many people Arc is the first time they’ve encountered vertical tabs as a feature.

never heard of it, but brave has a toggle for vertical tabs too.
