The ability to change the color of the dash and of the menu panels would be interesting, along with the ability to change the texture that they appear in, maybe something other than matte such as like a glossy thing, or maybe it looks like felt, something along those lines. Another idea is to allow for the creation and use of skins on them, so they someone can customize their dash to have their own icons for everything on their dash, and to have a custom skin theme for their dash and their menu. That would be so cool.
