I'll have a side of Consistent Window Behaviour with that.

The streaming music controls in 1.5 were fine and unobtrusive generally. The music controls in 1.6 are not. They're opaque and get in the way of chat text and minimized windows. Please make this a regular floating window that we can move around!

I think an option to not play streaming media automatically would be a definite plus. Instead of just having an all-or-none checkbox in preferences, a second check box to turn off automatic playing would not go amiss. That way the music controls are present, but only play if you actually hit the play button.

Also, it would be splendid if the camera controls would stay up when turned on, instead of having to toggle them every single time I connect to SL.

And while we're on the subject, having a convenient button on the camera controls to uncouple the camera from your avatar would be nice. Or even a menu option. Having the camera snap back every time I so much as twitch my avatar is annoying at best, and often a time-wasting repetitive exercise in resetting my camera view.
