Tried it and was disappointed that it was an additional thing that doesn't hide the default tab bar when enabled. Never ended up using it because of that, plus unreadable tabs is not a daily thing for me.
OK neat I found the setting that allows hiding tabs (so it's just groups again), better than nothing but I'm guessing I'd still need to use custom CSS to just... turn off the horizontal tab bar completely when using the tree menu?
You're almost there. Imagine a thing that was like a bookmark but also had its own individual history, and also kept track of where you currently are in that history.
Not at all the same thing. For one, you can open a history entry and then navigate back from that to the page you came from to that page - which there may be several. Tabs preserve per-tab history which makes it superior in many ways to both history and bookmarks.
fair point but in practice, I don't really see it being useful very often... You could write an extension to implement that feature so that tabs dont crowd your space...
Ah you don't have to keep all the tabs in view at the same time. There are addons like "Panorama Tab Groups" that let you only work with one group at a time.
