After growing tired of the Vista theme i was using, i realised that what i liked about it was the larger than normal “close” button. So i decided to make my own theme with nice, large buttons. I liked the idea of a big X to close windows and didn't want any colour, because that would be too distracting.
I made maximize/restore and minimize buttons, but a) they were a bit ugly, b) i never really used the buttons themselves and c) there was (and still seems to be) a bug when the buttons have transparency, that the buttons don't hide after mouse-off, so every time you mouse-over the semi-transparent buttons get brighter and brighter. I think it's in the bug tracker but hasn't been fixed yet.
Anyway, i made this theme for myself and the way i use the interface. But, if anyone else likes it and uses it, that would be great :)
