Being able to hide the activity bar puts VSCode into a class of editors I could imagine myself using. I tried it a couple of times in the past, and that damned big ass bar of useless icons bugged me too much (I work on a laptop screen 95% of the time, so giving up that much real estate for something I'd rather do with hotkeys is just painful). It sounds silly to dismiss it over such a small UI thing, but well...my screen is small, my eyes are getting older (so even though I have a 4k display, I can't shrink everything down without eye strain), and vim and Atom don't eat up the screen in the same way. So, I use vim and Atom (mostly vim, as old habits die hard). But, will give VSCode another try.
