As for the second thing, I see your point, but I’m not sure what exactly I can do about that without introducing some unexpected side-effect.

I would use it for just about all of my needs if I could get used to pressing F5 instead of F2… now I just use it for the mouse based interaction not a KRunner replacement.

…trying out alt-F5 has just made me realise something… Because I use pop-up on mouse-over Lancelot disappears when it loses focus which is what I want when using it with the mouse but it probably shouldn’t happen when I summon it with alt-F5. In particular I also use focus-follows mouse so any mouse movement (like brushing my trackpad) is likely to cause L to disappear. In contrast to this mercurial behaviour I have KWin set-up to keep KRunner on top I don’t lose it by accident (and skip taskbar so I can’t minimise it).

The same goes for Telepathy and Kopete.

But, still, for those programs that don’t use akonadi, this will provide a way to support them in L.
