Ok, sourcing of custom files is there. Hooks are there.

I was thinking a highlighted mode-line of the inferior R would be
enough. It's technically possible to make the modeline of all the
associated with current process buffers highlight but it would require
some modifications of the core. I will look into it. This might be
useful for tools like tracebug. Currently tracebug only highlights the
inferior modeline.
