Thanks for the suggestion.
The "widget" you are talking about seems to required some specific support from the host REPL, no? Could SLY do it? Could graphical Emacs do it?

I think the other problem is that it is easy to launch a new buffer in Emacs hosting the terminal emulator. But what I was suggesting was more like embedding a buffer inside an existing one. I don't know if Emacs has that feature, but if it doesn't, again there is no reason why someone couldn't add it. (I don't know if Emacs Lisp is sufficient to implement such a feature or if extensions to the C code would be necessary.)
