It drives me nuts that there’s no way to close a folder once you opened it. There’s no way to just edit a file without making it a “project”. In my mind that’s a weird design decision (which is probably rooted in weird fundamental ideas) and gives me no warm & fuzzy feeling about what direction it will take in the future.
IntelliJ is an all-out full IDE in the tradition of the old Visual Studio or Borland IDE:s, so it makes sense there. Zed is ostensibly a text editor in the same niche as VS Code, vim and Sublime, where I expect to be able to just open a single file and edit it without any bigger investment.
I typically have both an IDE and a text editor installed, for different use cases. But Zed can never replace IntelliJ and because of this design choice it can’t replace VS Code/vim/Notepad++ either.
