It'd also be great if there was a way to have neovim "wrap" arbitrary shell commands, kind of like rlwrap[1] does, only with full vim editing features available instead of the relatively crippled readline.

I'm hoping it's ported to Firefox when webextensions are ready.
> Actual uses an embedded Neovim instance to accurately manipulate each Sublime Text buffer as though you were editing the text directly in vim, without breaking any Sublime Text features (aside from multiple selection for now).
- It also breaks the automatic (while typing) completion and snippet suggestion popups (though Sublime's autocomplete has been wired into Vim and works great there)
- Sublime's undo works but isn't coalesced properly while you're in Vim mode (but Vim's works fine there).
