When I want to listen to all instruments, my typical workflow is to select/highlight a barline.
Yes, you can click on an individual note of a player anywhere, but this requires precision clicking. If you mistakenly select a slur along with the note, you only here that particular instrument.
Maybe I’m missing something obvious (it happens all too frequently) but my problem is that I cannot select/highlight the barline at the beginning of a system. So if I want my playback to start at the beginning of a system, I have to select the last barline of the preceding system.
It would be nice if we could select/highlight the beginning of a system for playback purposes.
