Feature request: improved drums cue note support

@Janus , take a look at this thread. Correct steps to make a rhythmic cue?. Also, besides the limitations described there, you can not enter or edit rhytmic cues directly in the drum staff or drum part since they are sourced from elsewhere which is not ok (other than initially as described). Then I don’t know if they are possible to combine with slash regions or bar repeats? Are they? Furthermore, I don’t think you can edit the cue notes from a font/size/stem length perspective (other then a global setting). Can you? Also, will the drum part and score drum staff show the same thing?
