The problem that I'm trying [in vain] to solve, is to ensure that every song in a show, while in the Perform Layout, plays correctly 100% of the time.
Again, the Perform Layout should be where everything is `set in stone', until the user makes a change to the song THERE and saves it THERE. Having to worry about whether or not the Document will be placed correctly in the Perform Layout, because it may have been changed in one of the other areas of SLM (such as in the Practice Layout), seems like an area that could be improved upon. Whatever layout is chosen in the Shows section, as the main layout for the user, should be where everything associated to a song is `saved', trumping, for example, how a Document is saved in the Document section, or anywhere else in SLM.
Am I the only user that sees value in such a feature?
