Terminal commands for installation from PPA:

sudo add-apt-repository ppa:screenlets-dev/ppa
sudo apt-get update
sudo apt-get install nowplaying-screenlet

• General: Easy translations through launchpad
• General: Wallpaper changer (Sets wallpaper according to the current artist or album) (requires gconftool-2)
• General: Cover Copy (Copies the current cover to the song folder) (requires imagemagick)
• General: History logging of the played tracks
• General: Right click menu: 'Open cover with viewer' and 'Open cover location'
• General: Sleep fade (Fade out volume, Quit player and Shutdown computer)
• Skinning: Ability to edit the cover image right before showing it (so you can make more flexible skins)
• Skinning: Rewritten the PlayerControls tag. (now supports transparency and don't have to be an actual visual group)
• Skinning: Added the transparency option for images
• Eyecandy: Fade effect for the following actions: screenlet startup, cover change, theme change, mouse hover, player start/quit, player play/stop, manual show/hide
• API: Volume control (with mouse scroll wheel up/down/click)
• API: Rating control
• API: Updated/Improved most of them and added some more

• The fade effect should be implemented directly into the screenlets engine so that all the screenlets can use it. I do belive that it would look way better.
