same -- I wish Helix would just have a full vi-compatible mode, it would probably be enough to get me to switch

the other thing for me is lack of the GitHub Copilot extension. I am far too used to having tab-complete. there's some effort for Helix extensions to handle this but it's not close to on-par last time I checked

I've tried evil helix and it is reasonable close to Vim, but still not quite the same (I don't remember but was running into several slight differences, which were causing enough adjustment that I gave up)

But why then switch?

from neovim to helix? I would prefer the configuration simplicity (while my neovim config is fairly stable and straightforward, it can be annoying to update) and better out-of-the-box defaults. I’d also be a lot more personally interested in contributing to the Rust codebase of Helix if I ever did run into bugs or features
