If you have the Audio Bus Manager window open and you add a new input, when you give focus back to the window it adds a new row for the new input but doesn't include input number, name or the settings cog.

Possible improvements
I do a lot of dynamic bus enabling and disabling. If that manager window could stay updated even when it doesn't have focus it would be an even more useful tool (maybe an advanced option that allowed it, and the performance stats window, to keep refreshing)

I feel it is worthy of it's own status bar icon to get quick access.
