Adding vertical tabs is already very useful to gain vertical space, however it comes with its share of problems (hard to read, new tab button that I would prefer to be on top, …).
Would it be possible to add a compact tabs mode at the top of the window like Safari does (and even more compact vertically)? This would make the tabs more readable, especially when few are open, and it would also save horizontal space compared to vertical tabs.
Thanks in advance!
