It would be great if macros were introduced for softkeys, even if it only meant limited functionality like 3 actions per press with a toggling light.
As for a use case, I’d like to be able to REASSIGN a channel from one group to another, so Action 1 could be assign on/off to group 1, and Action 2 could be assign on/off to group 2 set to be inverted. This would be more practical than scenes, as I could set up a key for each vocalist, and put any combination of them in the lead group or BGV group. It would be more visual as well, as recalling a scene would require looking at group routing to see which vocalist is in which group.
