In KDE 4.0.4 (in OpenSUSE 11), can't group similar tasks (xmemo, notifiers, acroread invocations, emacs, etc.). Consequently my panel is now completely useless. Please re-add this very useful functionality!!! Thanks.
This feature is still missing from KDE 4.1.0 (I'm using Fedora 9, and have the updates-testing builds).
I REALLY miss this feature from KDE 3.5. PLEASE bring it back!
