will it support on-hover feature?

[WinICE]

all other extension or default icon or text have supported the on-hover feathre ------- the icon or text will be highlight while the mouse pointer is pointing to it.

hope Window-Button can also support this feature.

and the icon should never be highlight is its operation is invalid(ex: there is no window)

my env is fedora 17 x64, the icon don't highlignt

depends on the theme for the window buttons - look at the style.css file in the relevant folder (example: themes/Ambiance/style.css). If it has a :hover style defined (on the .minimize, .maximize and .close classe) then hover should work (and let me know if it doesn't).

At the moment Zukitwo, Ambiance, Radiance, and Zukwito-Dark have hover styles defined, and 'default' doesn't (I guess I can add this in to the default style.css?)
