For the button script: the buttons worked well but when playing videos they are hidden no matter where I move them. It doesn't matter whether I'm in Fullscreen or simply maximized, there is no way to move the buttons beside the player module, or up to the menu bar (which are the only two "modules" shown while videos are playing). I tried skinned and unskinned modes too.
Fortunately, I have the mouse tilt button set to the shortcut key mentioned above, so this is a workaround for now.
I am thinking of using MM for more serious video watching because the sound is so much better than VLC. These buttons would be important in that case.
Any ideas about how to improve MediaMonkey? Let us know!
