They're in a bind because they are trying to straddle a market where you've got emacs an vim users to one side and Visual Studio users to the other. Some ability to customize the UI, even if it were provided by a plugin, would be helpful.
I should be clear though, I am not suggesting they strip it to the bone at the expense of other users' tastes. I just hate that I can't do that _myself_ because it's not quite as low level as Emacs.
I dunno, I'm old. I use directories and folders and hierarchical organization instead of searching when I'm allowed to.
VS Code is offputting enough and different enough in conventions from everything else I use that I don't have a great deal of interest in learning it's idiosyncrasies where they depart from standard UX.
