Any news on this?
Sorry, Pacman, my ass is still on fire, and there are few bricks left... But it is a rather simple layout, and I'm sure there is nothing you can't recreate. The album art is a simple $imageabs:
$imageabs(5,5,255,255,images/no_cover.png,nokeepaspect)
$imageabs(5,5,255,255,$directory_path(%path%)'\folder.jpg',nokeepaspect)
The info overlay is an $imageabs with a semi-transparent png and common titleformatting tags on top of the album art.
The mouse-over control cross is a combination of $imagebutton with commands but without images set + an overlapping huge button with an image but no commands (? when buttons overlap, both are executed).
The seekbar is really easy to make even if you aren't so much familiar with the WHS Panel Mod, you can even just remove the text from the default panel.
I'd really like to get back to it myself, but all this running around just kills the zen
