- The arcade buttons push in.
- The arcade player icons are flat with clear boarders.
- The keyboard buttons push in. You can insert text to label them. (offset is 20x20 - 11pt font as shown)
- The music player controls highlight when entered, and turn red when pushed.
- The slider controls are 2 parts. The rocker and the level bar. The rocker highlights red.
- The bottom push knobs only push in.

Anyway, making custom buttons isn't that hard so if you need any for your skin let me know.
