Funnily enough, I started hacking away at the Winamp Modern theme just today, aiming for a flat, minimalist, Metro-inspired look that matches my Windows desktop.
Here's what I've got so far:
Only really had to edit one maki file so that's nice.
I don't have any experience with skinning or design or anything like that, so you know, goes to show it isn't that hard to get a handle on.
Oh, and if anyone knows how to edit the vertical width of the "artist/album/track" column headers, I would be grateful. It's the only thing that has me stumped, and I don't want to make the scrollbar arrows bigger just so it aligns...
