Thanks, I don't remember now if it was all me :)  it was discussed if we
could have yet another output in [inlet~] to show number of connections,
but it ended up being something too specific. This is the only use case for
me.

Now...... I already have created my first multi-channel aware external, one
that detects the number of channels in a multi-channel signal connection. I
found it useful for my [else/out~] abstraction, which now can detect if on
the left inlet we have a multi-channel signal. If there's one, then I
distribute the channels to both outputs :) if we're doing a check to see if
there's a mono input, we could also do this now in the new [output~] object
since the next version will support all this ;)

So maybe I can propose we add such an object into Vanilla. This same object
could maybe also show if a signal is connected, so we can plug the outlet
of [inlet~] into this new object and we wouldn't need the 'clever hack' and
also get number of channels. This object could be called [sigstatus~] or
something.

My object only detects number of channels and it is called [nhcs~]. Here it
is in action inside my [out~] abstraction. I don't have other examples but
I think this could be useful for other stuff, maybe other can think of more
use cases.
