show/hide staves using the mixer

hi guys,
here is an idea i've post for in the bug tracker here : http://musescore.org/en/node/25085

the idea is makes musescore improving readability when editing staves on complex score. So the idea is simply use mute / solo button in the mixer to show/hide staves in the score.

For exemple, I'm working on a full symphonic orchestral score, and want to wirte strings arrangement. I can use the mixer and check solo on violin / viola / cello /double bass and it results in my score i only show those staves.

Another example, I'm working on a complex polyrythm arrangement between 5 percussions, I can use mute to hide 2 or 3 staves and work on the others.

Thanks for your comment.
