Hi Stefan...

Maybe a bit off-topic... but somehow related:

Is it there a way to show the current capf backend for example in the
mode-line?? Company has such thing, and it may be useful for example, to
know which completion-at-point-functions is working better than
others... Because sometimes different functions generate similar
outputs and it may be useful to know which are the one in use, specially
when exclusive is false in some of them.

Any Idea?
Best,
Ergus.
