Scott Ahlsmith: I'm glad we could help out!

Mute/Unmute options are a nice idea - we'll see what happens there.

System (global) volume control is found at the very bottom of the screen, below the playback controls. If you're not seeing that, we'll need more details - contact us directly for support.

Timed On/Off - This would really be an Airfoil feature, and I can't say it's one we're likely to add. We'll see though.

As far as Pandora goes, I'm afraid I don't follow. In Airfoil Remote, you select Pandora and it launches for playback. Later, you want to switch to Firefox (in Airfoil Remote again?). What happens, what's the issue?

As I said, I'd recommend getting in touch with us directly for more!
