Never thought of Zed as Sublime replacement, but now that you've mentioned – why not? I use Sublime only as blazingly fast temp note taking that doesn't lose them on exit, but I see Zed fits the job perfectly. One less close product hopefully!
Ever thought about Heynote? https://heynote.com/ I love it.
yep that lycra wearing bike rider from North Sydney doesn't need more of your money
Sadly this is how I use Sublime as well, though not anymore, on work systems the new Notepad app has tabs finally, and can do exactly that...
