I would love to see a list per scene of the used Hotkeys and their associated Variants.
I realized you can look at each variant and see which hotkey is assigned, but it gets complicated when you are sharing scenes with others. In several places I've worked it is not unusual to get a quick turn-over request to (for example:) replace old surfaces for updated ones and have it ready for review A.S.A.P. I may be handed someone else's working file and need to quickly figure out which hotkeys are not taken, to set up Switches. This would also be useful in order to print out a "cheat sheet".
