Sublime Text and VS Code both do the same thing. I can imagine that it takes a bit to get used to, assuming that you'd even want to, but I've found it to be very handy: At this point in time 6 unsaved text documents open in Sublime Text, covering a variety of subjects that I haven't quite finished working on, or that I just want to remember for later
How so? None of this would more than mildly inconvenience me if it were lost. Important notes/files are of course saved in appropriate locations, but a lot things aren't that important
