Here are the modifications for the skins between RoadRunner and EniCar.

For IGuidance native support added a few button command.
IGMENU, IGDESTINATION, IGNORTHTOGGLE, IG3DTOGGLE, IGZOOMPLUS, IGZOOMMINUS

BUTTON now support(in V0.10) the addition of animated gif for their different state. After each button in the skin you could add some eXtended information.
Example :
B,292,533,98,69,"PLAY",
X,POWER,"Play_Start.gif"
X,NORMAL,"Play_Idle.gif"
X,SELECT,"Play_Down.gif"
X,OVER,"Play_MouseOver.gif"
X,IN,"Play_GoIn.gif"
X,OUT,"Play_GoOut.gif"
an X command refer to the last button.second parameter is the state of the button, third is the animated gif file to use.
The States are :
POWER : Only displayed when the page appear..
NORMAL : Normal draw of the button (idle state).
SELECT : When the button is Selected.
OVER : Mouse Over state.
IN : Between the normal and select state
OUT : Between the select and normal state.
Of course the IN and OUT animated gif should be very short as the button will wait for the end of the animation to change to the next state.
