I really like the greater transparency of items I mark to be ‘non-playback’ (like turning off the playback of a trill indication when a timpani is triggering a rolled sample for playback.) I think this transparency is a Version 6 addition maybe? I don’t remember it in version 5. Bravo!
I just wish I could make it slightly more transparent (is there a setting I’m missing - I don’t see it in the voice color prefs) or actually have non-playback items be a certain color. It’s almost unnoticeable to my aging eyes.
