I don't know if this request has been posted before, but I'd like to see a mod in Xion that allows for changing the skin and playlist colors, like in AIMP. Or in some of the new RainMeter skins.....You know, a button-object that loads a full color-picker.
This I think would be a fantastic addition to Xion, and make even more people want to use the player, so that users would no longer have to search for a player that matches the colors they have on their desktops; they could just adjust the color with the color-picker to the color they want. This color-picker should also change the playlist color. The only problem I see for enabling it in the playlist are the other colors, like when a file isn't available, etc. But perhaps a separate playlist color-picker thingy, allowing for changing the hue of each playlist text variation could be implemented?
...Anyway, it's just an idea.

This is really great btw! Perfect. Ima update some of my previous skins anyway, and now I can add this! Sure cuts waaayyy down on the number of interface documents in one skin!
