Oh, it seems that many things aren't that obvious as I thought they would be... Maybe they become a bit more obvious when you use the player, though.
To answer some of the questions: The current song is always the blue entry. All the grey entries above it are the recently played songs. Everything below is what comes next. In addition, the artist and title of the current song is displayed at the head. Those aren't input boxes (although they might look as such). The clear button clears the queue. The volume is the slider on the right.

But I agree: The GUI needs much improvement...
