As an aside, it would be straightforward to make vim/neovim the editor that opens when you double click a text file on the desktop.

This kind of setup is at its most powerful when you live on the command line though. For instance, you need to modify .py files across multiple projects that mention a certain variable, have a certain word in their name, and were modified within the last month.

That search is a bit easier in bash/zsh than it is in most IDEs and the strength of vim/neovim is the shell integration.
