Group Channel mono or Stereo?

Maybe I’m overlooking something, but I just tried to start a template and created a bunch of stereo and mono group channels.
Turns out there seems to be no way of finding out which channels are mono and which stereo. Not in the mixer nor in the track inspector nor in the Edit channel window.

What am I missing here?

Thanks for the tip.
I checked how it was in C6.5. Turns out in C6.5, it’s only indicated in the Edit channel window.
Should be clearer though.
