I think we don't have much of a choice. We'd need to coordinate this with

I appreciate you looking into it.

I just removed plasma-widget-menubar from the Kubuntu seeds and from our
default panel configuration for netbooks because I think that having a solution
that only works for some applications and not others and users have to know
implementation details like what toolkit it was developed with to know if it
will work with it or not as being too broken to ship. I'll certainly stop
I think too broken.
