Good!  Some of these are very subtle (the markings were added by me,
and i'm an absolute perfectionist).

Yup, there is little time left - only 30 hours.
Some ideas for ties:
- put some/more constrains on how much ties can move vertically
- don't allow tie ends to touch stafflines
- allow ties to be more arched
- treat ties in chords differently than those connecting single notes.

and slurs:
- slurs should be allowed to cross stems
- slurs should either cross stems of flats and naturals, or clear them
- they shouldn't touch
- slurs broken across line break should start later than they do now
- broken slurs should be sloped smartly
