This is a real nit-picky thing, but it would be nice to fix somewhere along the way.
I have a project with a dozen flows. Several of the flows swing and several do not, so I cannot use the playback option for swing, as it applies to the entire project. I added the Medium Swing tempo marking to my flow. That works fine for all the instruments with regular notes. However, I have chords set for playback. If the chords fall on the offbeats, they are not swinging. They play exactly halfway between the quarter notes.
It is not a big deal, more a curiosity. And I realize the chords are system-attached rather than connected with particular instruments, so this probably complicates things. But if I have a swing tempo marking for all instruments, I would expect the chords to have the same timing.
In the example below, the trombone swings but the piano chords do not swing.
