To be clear, this plugin is only a keymap, and just extends the built in Emacs-style keymap option of VSCode. If you did much/any mapping of any keys in Emacs, or are looking to expose more Emacs-like features, you're SOL. VWCode is simply unable to support most Emacs editing features without a significant engine expansion, and that's beyond the ability of plugins to add.
First time hearing about the Helix editor, and I gotta say — it really caught my eye. I’m not super familiar with Vim, but I’m definitely gonna install Helix and give it a try.
