Hard to select notes
I find that clicking on a note to select it is much harder than it has any reason to be. As often as not, I'll end up accidentally selecting the note stem instead. I'm not sure why I would ever want to select the stem separately from the rest of the note. It certainly isn't something I've ever wanted to do. But it interferes with regular note selection, which I do constantly.
Do stems really need to be independently selectable objects, distinct from the notes they're attached to? The only common reason to select a stem is to change its length, and that could be done just as easily if it were treated as part of the note. The inspector for a stem has only four items. One of those (Visible) is redundant, since the note's inspector already has a "stemless" option. The other three (Color, Horizontal offset, Vertical offset) hardly even make sense. I mean, why would you want to offset the stem away from the note it's part of, or display the note head and note stem in different colors? But if those really are important, they could easily be added to the note's inspector.
