selective play of staves

First of all: thanks for the fantastic software! Keep on going!

My requested feature:

During score development (especially with multiple staves as used by brassbands) it could be very useful to have the option of "switching on / off" the playback (play) on each individual staff. As a score develops itself, it helps to be able to focus on just a few staves in playback, instead of allways hearing all the staves.

This option could probably best be implemented as a "play" checkbox after each staff in the "create instruments" panel.

To enhance this further, a button could be placed in the "Play panel" with a "Edit instruments..." function (and this could map to the "create instruments" panel.
