Input note (predictably) does not always change when entering/leaving note mode
Currently in the 2.0 Beta 1, the note duration changes when you select a different note while not in note mode (expected) and does not change when in note mode (expected) but does not always change when leaving note mode on a note that has a different duration. This can be fixed by leaving note mode and entering note mode again (see http://www.gfycat.com/KindlyVeneratedKitten [too large for attachment]).
1) select note of different duration while in note input mode
2) leave note input mode
3) observe that the duration does not change (bug)
4) enter note input mode
5) leave input note mode
Then the note duration will have changed.
