One of the things that got me most annoyed about GNOME was the fact that they grouped up items in their theme to share with other elements. KDE have done something similar with the Plasma theme, what looks like hard coding tasks to the same state in the add widgets ,which pretty much breaks my Gaia design look due to it being a dark panel and white widget backgrounds. KDE have done the same for krunner as well, hard coding it to be themed by the top panel. WTF KDE, WHY? krunner has it's own SVG, now it's useless.
It really annoys the hell out of me, it was fine before. One possible reason is that Air looks the same, especially with the theme being the same colour across all widgets but it's just lazy, when developers know full well that we theme makers need as much flexibility as possible. Seems to me that KDE have got lazy and made a retarded design decision, sorry lads but you did.
And no, I'm not going to storm into freenode #KDE IRC chat and tell them what I think, been there done that and have the bruise on my head from the brick wall I smashed it on, though GNOME's brick wall is much, much thicker.
