right, and this is shell specific as to what that even means. (remember that we 
have a KPart too :)

we'll need some mechanism to get to this information, and wherever we place it 
it will need to be available to things such as tooltips and dialogs ... as 
long as we talk about Plasma code only, i'm not sure what better place than 
the Corona related to the Containment/Applet in question there is.

but the real complication comes from the fact that we'd like to make the 
tooltips available to other applications ... ones which won't have a Corona. 
so this information will still need to be provided by the shell/application 
itself .. we may end up with an interface which applications can reimplement 
or just instantiate to get the default behaviour, which Corona itself 
subclasses or aggregates so it can be customized in behaviour.

question is how to make this visible to components that need it, and that 
sounds a lot like needing a singleton ... if we can get away with an 
application global singleton it's simple. but the case where there may be 
multiple Coronas in the same app (think about the KPart :) that might not be 
true.

fun .. :)
