Pauses/Breaths before notes
It's a small feature but could be very useful in playback. Sometimes a movement of a piece may have a repeat bar at the end, and transitioning between movements when they are finished usually should have like a 10 second pause. But adding a breath in the final measure of a movement will make it occur before the repeat also, throwing the playback completely off. If breaths had the ability to occur right before a note, they could be placed right before the note of the following movement so that repeats aren't interrupted and time between movements is still reasonable. It may seem kind of unimportant, but I think it would be a real nice addition for moments when it's needed, especially in my case.
