Rhythmbox, unlikely other media players, is still wasting a lot of vertical space. Its use on netbooks is off limits.
To improve this situation, let's move song progression bar just into main toolbar.
There's a lot of room to accommodate it on the left of volume level icon, and it's hard to justify someway all the vertical AND horizontal space it's taking now.

let's do something good for our favourite music player (for its users :)

thanks, looking forward to a stable 3.0 release!
