Piano Roll Editor Feature requests: editable note velocities ...and more

I have three feature requests for the piano roll editor:

1) Make note velocities editable. It is cumbersome adjusting multiple note velocities using the inspector. It would expedite the process if note velocities where editable in the new piano roll editor.

2) Display measure numbers and the vertical play-head line even when the upper view of the editor has been minimized. Currently, If the piano roll's bottom graph view is extended all the way up, both the bar numbers and the play line disappear (see image). This could be remedied by assigning the measure numbering to its own row and by extending the vertical play line all the way down into the bottom where the velocity and other note attributes are graphed.

3) Add an option to keep the piano roll dialogue always on top. Currently, the piano roll editor "disappears" when clicking on a score. Being able to keep the editor always on top would allowing easier back-and-forth navigation between the score and the editor.

All these features would be particularly useful in analyzing and editing the velocity graph of an imported live-performance midi file.

Thanks,
Sam
