Version: (using KDE KDE 3.5.5) Installed from: SuSE RPMs Panel has such feature as setting either the app is native KDE or not. KMenu should also have such option.
I don't understand, what would this feature do?
I have no clue, I don't know anything about internals. But I mean, the same as for panel. I can only see the effect -- without this options some apps won't start.
I don't think this request is still relevant in the context of KDE4
