I'm not sure if this feedback is useful, but I have to say that a collaborative text editor doesn't feel like that big of a sell.

Pairing in VS Code over Zoom has gotten a lot better over the last year or two, to the point that I choose it for simplicity over more purpose-specific tools like VS Code Live Share (which is a bit slow/glitchy but fine, and overall "neat") or Tuple (which is great).

Would I pay money for "VSCode, but faster"? Absolutely. I'm waiting multiple seconds for keystrokes to apply sometimes and don't know why. But the extensions are what make it VS Code – if I just wanted "a faster text editor" I'd uninstall all my extensions and just keep using VS Code (it'd blaze), or switch to Sublime.

I'm excited to see more people working in this space, so I certainly wish you luck!
