“Snapshot all” would probably be a way to solve it I think. With the snapshot checkbox (I don´t remember the correct name right now) I can control which widgets are to be saved in the snapshot and which are not.
And with a nice “snapshot all” button on top of the rackspace I would have a fast way to store what I´ve set right now and what appears to work best in a band context. This would be possible then even during playing the verse, before switching to the chorus.
