Totally: I couldn't stop thinking about actually generalizing this to a workspace/desktop so I could apply similar principles with multi-windowed Emacs — a window manager that also connects windows ;)

Looks really intriguing, but Emacs is really hard to leave behind.

But I do believe this pattern applies to more things than just IDEs, and might even replace multi-workspace setup. Keep at it and hopefully you are successful and this pattern keeps evolving!
