More flexible score navigation: Jumps, Volta, etc.
MuseScore navigation/playback works well with in the framework of classical music, and most avenues of other styles.
I have a score with the form AA BB AB C BC ABBC. I don't think MuseScore can manage this, nor would I want to try to coax it to do so.
I come upon this need more and more frequently. For instance with a score that takes the form shown below.
It all goes well until you get to the fifth line of the sequence. However with flexible jumps I could fit the score on two pages, but without them it would take three or four pages.
