Trying it out again now, this isn't Vim, it's an entirely different product. It doesn't have command editing mode q: nor q/. It doesn't use Vim's regexes and doesn't support \v (which is probably good, Vim's regexes are very bad, but it's still not Vim). There is limited support for windowing, I mean not really support at all, because this is a better windowing system that Vim (:h CTRL-W_J). Although I am surprised `ctrl-w +` works. Of course no support for Vim plugins like surround.vim. Vim out of the box is not a usable editor. H and L seem to be busted and scroll the screen.

Still trying it, no `:norm`, no `:g`, multiple cursors in VSCode are so much more powerful than this, and already do 90% of what you want to do in Vim in the first place.
