As a result, Sublime ist the only commercial (locally installed) software I still use, and it is always open.
There are situations, where I use macros, regex substitutions, or browsing the file system (using the keyboard only for speed) when I prefer to use my other editor, Emacs.
I recently played with Zed, which looks cute, but I immediately lost an important file, so back I was in the Sublime buffer. (Both Sublime and Emacs always auto-save documents without explicit "save" action, so you can never lose anything.)
I tend to have many Windows open (several dozens), some of them for several years, others for five minutes. The only two features I would like are: - search across all open files and - a list of edit buffers that is itself an editable buffer that you can walk around using cursor key and select a file by hitting RETURN like Emacs has it.
Generally, I prefer that I doesn't become a feature overloaded big monster of a program that can do everything (that's Emacs already, but I like both, I just want them to stay different).
Although for longer-term programming of bigger projects I prefer IDEs like IntelliJ IDEA or PyCharm CE, in recent time, I had to write mostly small programs, and both Emacs or Sublime fit that bill (no need for language servers for me for two screens full of a Python script as I also teach that stuff).
Zed has an "autosave" setting, it's just off by default.
Basically I just feel guilty that I'm not using a "proper" note taking application when so many of them exist.
And the solution to getting it synced is to back up your computer, which you should definitely be doing.
More broadly, though, I don't know that I consider whole-system backups as important as I might have once. All my local important docs are in Dropbox, and all the code I'm working on is regularly synced out to git hosts. Other than some unimportant Fusion/Bambu projects, most of what I'd lose is honestly that same kind of ephemeral context that unsaved Notepad++ files are: terminal history, browser bar completions, my downloads folder, etc.
