The button to turn the visuals on/off is a toggle, this is how its setup internally in RR.
It is possible to setup state flags, in the initial 3.0 skin release this is exactly how it worked. But like i said, the visuals are broken and its part of the reason why the state flag code was pulled from the skin.
the about screen in the skin will show you the proper version number.
YES
this skin does support HD radio. I cant really state any opinions on if its fully supported or not, i dont have the hardware to test it, and also the HD support was not added by me, but is included.
ill check the server to see if any of the files need to be re uploaded due to corruption.
