I'm using an iPod Nano 2G with RockBox 3.10. Everything is wonderful.
I found this theme - Electric Bars of Colour - it just looks beautiful on the while playing screen.
The only problem is that the progress bar doesn't work at all. It's just the dark green one that's part of the background.
I tried looking into it myself. The %pb line in the theme file seems fine, but then again this is the first time i've ever looked at rockbox code.
The pb.bmp file is in the folder.
Here's a low-res picture of my iPod, lol.
And if you can fix that, I'd also like the area dedicated to showing the time elapsed/total time of the song to be longer. The font that I'm using gets cut off.
I've attached the .wps file
