Some general feature requests

Hi! I love musescore a lot, I've been using it for over a year now.

I've been thinking of some general features that I feel like should be implemented. Please tell me how possible (or impossible) it would be to do so. Thanks!

- The ability for a crescendo/decrescendo to change the volume of a note mid-note (for instance, increase the volume of a whole note as the note plays). I understand this has been asked before, I'm just curious if there has been any word of that being possible.

- Glissando playback. Again, these DO already play back, but it would be awesome if it possible for glisses attached to Trombone and Vocal parts to actually slide, rather than play every note between the two attached notes. The closest thing we have so far is a bend, which has worked for me in a pinch, but it would be great for that feature to be built in!

That's all I have for now. Please, tell me if either of these have already been confirmed as possible. Thanks again!
