For a brief moment, I looked into a sort of VS Code plugin for CodeVideo but I realized it would be tough with things like mouse and animating typing directly in VS Code (unless I did a complete fork like the Cursor path). But I wasn't quite ready to take all of that on.
But yes, I think it's a huge latent space that hasn't been addressed anywhere in the market simply because you need to go half insane to take something on as complex as replayable state management for the IDE.
