Score Editor: Playback of Grace notes and Glissando + Glissando Display


We know that Score editor does not play grace notes.

Now sure if it is good idea to put three features at once, but they are very similar/related.

FR 1. It would be great if we could have the option to Grace notes and with preference to play then on the beat ( as in Classical and Baroque I suppose).
FR 2. Glissando playback.
FR3. It is know that the score editor cannot place glissando properly! notes to notes, or hard ( chord) glissando) ]

I suppose FR1 and FR2 would be hard for the programmers to implement. Specially if they could for FR3 give us option just like human playback in Finale.

What do you guys think?
