Yes, no doubt we need to keep KAction and most derived classes, however all of 
them now inherit from QAction.  A few derived classes are superfluous and 
I'll clean them up at some point.

KAction itself provides above + beyond QAction:
* default shortcuts, user configurability flag for shortcuts
* global shortcuts now :)
* saving and loading of customised shortcuts
* automatic Kiosk integration
* an easy way to upgrade QToolButtons to (potential new class) KToolButtons 
should we ever find it necessary
* integration into KActionCollection and shortcut configuration dialogs
* backwards compatability api (quite important, especially plug(), 
isPlugged(), and signal activated())

I think we'd be better off modifying KGuiItem to more closely resemble basic 
Q/KAction data.  Probably would be better with a nicer name too.

Yes, pretty please :)  I think this is essential...

Yes, I'm surprised by this comment too.  I heard such a widget would be easier 
to implement in Qt 4.2, but it still won't have the rich features (column to 
search selection, etc).
