Helix itself looks amazing, but the keybindings make me stay away from it. Even if they are better than the original, I don't want to learn another set of "non-standard" keybindings that I need to switch between only to use an editor.
It's the opposite for me, the keybindings are the best feature IMO. It's like all the niggling little things that didn't make sense back when learning the Vim keybindings, have all been removed and replaced with things that make more of a coherent whole.
I can't use it yet because of the lack of addons/an ecosystem, but I hope to one day either move to helix or bring as much of this sensible keybindings system over to neovim as possible.
