Definitely tough to "compete" in this space because locally most people end up going to their IDE of choice for heavier workloads and if you do decide to use a terminal editor, you'd rather have it be compatible with things you'd encounter in the wild (e.g. a remote server, someone else's machine).
That being said, this is cool. I've set it as my default editor for the GH CLI to use it for pull requests and the like, let's see how it goes!
The ergonomics are so much better than vi/vim/nano that it is my go to edit from the CLI tool. Sometimes it's faster to just edit a line than mouse over to my IDE.
And yes I think vim has bad ergonomics. It's so much effort to get it configured to work for me. I get way more out of Alfred and my moonlander keyboard with macros that work across the whole OS.
A moonlander keyboard makes for an interesting comparison here:
It's worth taking time to learn something to get a better experience. Keyboard layering takes some time to get used to (especially if you can already use a standard keyboard), but is worth being able to reduce hand movements. Modal editing takes some time to get used to, but provides a richer navigation/editing experience.
Similarly, you can customise your moonlander to the point where it's yours and no one would know how to use your keyboard.
