I’ve a conflict with your approach. The “bold-back” click for going to the “Main Menu” is a global action (non contextual). We had a nice discussion about this some time ago and everybody (more or less) agreed that we wanted a “non-contextual and immediate” action for jumping to the main menu.
Of course i understand your POV, and agree the current “control-screens” workflow is sub-optimal. We must improve it. So … let’s take your proposal and think deeper. Perhaps we could find a better way
