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.
Edit, I suspect what I wanted was the "after delay" setting here https://zed.dev/docs/configuring-zed#autosave
