I tried to log in to check whether things had improved, but apparently I need Google's permission to do so now? And, in fact, nothing will run without allowing Google's JavaScript, even once I've logged in.
Anyway, version control is there now, and you can edit existing Git repos! Except it's actually GitHub, not Git, so I can't use it for any of my existing projects, including my programming language…
That being said, I think the world is better with Repl.it in it. It's not like these other things I criticise where I think we're better off without them; Repl.it's flaws are infuriating because they're stopping me from appreciating something potentially great.
