@airforce25228 i meant that the tab island when minimize it becomes a line. So it definitely so much thinner than a tab

Of course I mean the same thing but this could be problematic (in tab organization ways) and I would make it ate least optional. It saves some space for sure but also thin line is useless when you search some tab or want to make some overview about your tabs. So have some tab with icon and short description makes much easier to remember what is inside and easier to track your tabs and stacks.
