ah I *love* EWMH for being that precise ;-) Personally I would say it's so weak that an application using Desktop or Dock cannot rely on all desktops implying skip taskbar. I just checked KWin's sources and KWin also does not apply any window type checks (though we have a wantsTabFocus which restricts to Normal or Dialog). Given the high regression potential (windows which used to be included aren't shown any more - yes the one user's bug is the other user's feature) I would highly recommend to not change the behavior in 4.11. For KF5 and Plasma Workspace I would suggest to adjust KWindowSystem framework to imply SkipTaskbar and SkipPager for some window types. If I see it correctly only Dialog or Normal should be shown in taskbar and pager. Cheers Martin
