Jon, what I meant was, with snap on, the eighth note is displayed simultaneously with the first sixteenth note. (I'm not sure how it sounds. Also, I'm not sure what the resolution is, but it's the best for the notes I'm entering.) When I enter a sixteenth note and then increase its length to an eighth note, it will be adjacent to the first sixteenth note and appear as an eighth note (and have the right sound). I also notice this problem when there are a lot of rests and syncopation. It's possible to change the resolution for a few measures, but for me it's just easier to enter a note at the correct position, then change its length.

I like the numbering idea too.

I noticed on one song that there was a "harmony" note in one place in the melody line. I left it out because it sounded confusing.
