Playback should start from current selection
If I want to play a section of the score, I click at the point I want it to start playing from and then press play. But I have to be very careful what I click on, because it only works if I select a note head or a whole measure. If I instead select anything else—an accidental, a stem, a slur, etc.—then it ignores the selection and just continues playing from wherever it last left off. I suggest that if any score element is selected, that should serve to set the starting point for playback. Then I could just click wherever I wanted it to start, without having to be careful about exactly what I was clicking on.
