I've marked this as upstream because I think this is much better done in VSCode itself. I don't think we can do a satisfying job ourselves (for instance, making it work with mouse clicks is impossible, and to get a cursor over there, we'd actually have to add that whitespace to the document, since VSCode doesn't actually have virtual space, which would likely cause problems or at least VERY significant complexity).

@J-Fields I've been recently replicating my vim/tmux setup in VSCode and I've been surprisingly happy with it. The driver was to get a better workflow with copilot chat / edit versus what's currently available in the terminal domain. https://aider.chat/ shows some promise, and I forked a vim plugin to allow it to sort of work inside neovim, but it's definitely not as slick of an experience as what VSCode offers. But I digress.

My main question is - one of the things that trips me up on almost all editor movements is that I greatly prefer to have my vim setups use virtualedit=all so that the cursor can go anywhere. This helps me get to where I want to go without any horizontal cursor jumps which often land me not quite where I want to end up.

Just asking your opinion, I guess, is there any hope that VSCode upstream will ever add support for virtual space? Based on your other comment here, it sounds like that'd be a necessary prerequisite to having this feature in the vim plugin?

Thanks for your time! Cheers 👋
