Another Type of Repeat
Musescore has just about every type of repeat except repeating a group of notes in a measure. To see more like what I mean go to the Header that says "Patterns of groups of three or more notes" here: https://en.wikipedia.org/wiki/Abbreviation_(music)
As you can see there is a special type of repeat (that happens to look similar to the thick caesura on Musescore) that will repeat different notes within the same measure. Hopefully Musescore will add this feature as it will save pages when many fast notes are repeated. Thanks for reading! :)
