when you double dot a 1/8 note, you're left with a gap that is 1/32.
similarly, a single dot on a 1/16 note leaves a gap of 1/32, and a double dot on a 1/16 note leaves a gap of 1/64.
right now there is no way to place a 1/32 or 1/64 note, so to make a complete measure the only way is to use another dotted note.
some possible solutions:
allow placing 1/32 and/or 1/64 notes if there are dotted notes like this
disallow users from making double dots on 1/8 and disallow all dots from 1/16
we should gather user feedback to decide what to do
