I've planning planning the next major app version, focusing on updating some of the workflows to make the functionality more intuitive. The ability to change or customize song layouts is one of the most confusing functions, probably because it is hidden behind a tiny "layouts" button. I plan to move this to the main menu along with Songs, Shows, etc.
I also plan to move some settings from the overall Settings menu into the layouts so that you can have different settings for each layout. For example, you could have one layout that starts a tempo and recording when you select a song, for use on stage, and another layout that doesn't, for use in rehearsal. Or you could have one layout that plays continuously through recordings, to preview your set (I like doing this while driving to a gig).
Since layouts are now gaining a functional aspect as well as a visual aspect, it might be best to rename them. What would be a better name? Pick an option above, or write your own suggestions below.
