We would love to be able to have an app that would serve as an electronic music stand where musicians can switch between songs with one swipe like turning a page, and pre-download sheet music or lyrics or personal song notes they make during rehearsal. These are attached to their account/device so that they can see their preferred lyric/sheet/notes whenever they do that song. Then during the service they can go live and all the music stands are synced to go to the next song at the same time when prompted.

I know that Planning Center Online has this feature and since we switched from PCO to Elvanto, it has made our musicians do extra work without this feature.
