one thing that appears in many of my compositions but never types well in MuseScore is that multiple voices in one staff overlap. Images are attached.
Here, two voices begin the measure with a two degree interval. But the notes should behave as if they were in one voice, with the half note shifted to the right of the whole note.
In this picture two dotted half notes (using the same voice) are in a two degree interval chord, but the dot from the 'e' is placed inside of the head of the 'f'. The two dots should line up vertically where the second dot is.
Perhaps this is supposed to happen, but I'm sure if two notes in the chord an octave apart then its accidentals should line up as well. The naturals above are pushed out farther than the ones below them; same with the sharps. This is strange to read but also takes up space.
This is just another picture of two voices overlapping, but this time they are the same note. Like before, the eigth note should be directly to the right of the whole note.
Sorry that's a lot... I hope the pictures show up.
