Switch between projects + permanent mute+videobug?


I have 2 questions: First of all is it possible to choose which project you make active when you have multiple projects loaded? It seems like I am only able to select the newest one I opened?

Second: Is it possible to mute a track in a way that when I unmute everything the selected track stays muted (like permanently unless I unmute it seperately?) I was actually hoping that hiding a track would work, but it gets unmuted too when I mute everything.

Third: Sometimes when I playpack video it stops playing. This is kinda frustrating as lately Im doing sounddesign and compositions for some movieprojects and I am really dependant on this. Anyone knows what could be wrong?
