I have no idea about presskithero... But we can't just use a closed platform for our stuff. As for the first question: we, obviously, use Krita for icons, headers, banners and screenshots, but that's just because we're making Krita. It's not what Krita is made for :-)

And don't even think of trying to make mockups for whole websites in Krita!
