It's worth mentioning that Emacs operates on files the exact way you want Zed to work (on your philosophy page). I'm not trying to be one of those "Emacs already does this" guys, but you seem to legitimately think it's a new concept, when most people using Emacs use it like that. "Like that" being that we don't care if a file is open or closed. If I'm swapping between 2 files a lot, I will just swap buffers, but usually I just navigate straight to whatever file I need and open it. If it's already open, the buffer will come up; otherwise a buffer will be created. ido-mode makes it trivial to query files/buffers: https://www.youtube.com/watch?v=lsgPNVIMkIE https://www.youtube.com/watch?v=lsgPNVIMkIE (edit: inversely, ido-mode actually saves a history of opened files so if you try to switch to a buffer of a file that isn't open, but you've opened before, it will transparently open it for you and it feels like it was never closed) Also, same thing with file creation. I'll just navigate to the file I want to create and hit enter.
