AHA !!
We have our first example of a non XYZ navigator.
Here's a first shot, probably gets refined or binned, but here goes:
WidgetZone Sends
Rotary1
...
Rotary8
RotaryPush1
...
RotaryPush8
WidgetZoneEnd
NavigationZone SplaySends Alt+Select
Sends
NavigationZoneEnd
Alt+Selecting a Channel causes that Channel's Sends to splay out on the rotaries.
Alt+Selecting another Channel does the same thing.
Alt+Selecting the currently selected channel takes you out of Sends mode.
So far I like where this Navigator concept is headed
