Fresh kubuntu 15.04 install (so: using plasma 5.2.2). I happen to like the classic Windows look (it also really confuses people :) ), and in previous releases I've installed the kdeartwork (or some such) package, and it appeared in the Workspace Appearance section of the system settings.
Well, that selection is no longer available, and no additional themes are showing up in what appears to have replaced it ("Workspace Theme").
(Note that this is different from the "Application Style" setting, which sets colors for titlebars etc., which still has a Windows 9X selection, but that's not what I'm looking for).
Help?
