Oh yeah, VSCode's autosave has saved me hours in otherwise-lost code. I do make frequent use of its hot-exit functionality, too.

While that's great, I wish the same thing existed for a lightweight Notepad-esque app, too: I used ++ a lot for quickly jotting down information while it was being read to me (so, on the phone); having to start a full-blown IDE for this seems wasteful, and not the right tool for the job.

Perhaps the solution is just to leave VSCode open all the time, but that wouldn't work either: whenever I switch workspaces, I'm asked whether I'd like to save the unsaved files (so, just like Kate), and it can be quite resource intensive. Grr.
