looks already nice ;)

not sure this is actually reducing the clutter, because goes from something 
shown only on moseover to stuff always shown.
maybe still reserving the space for the title/buttons, but still show them 
only on mouseover

like the grid approach, not sure how will be received not being able to put an 
applet of "exactly that amount of pixels"
probably grid cells should be quite smaller than the ones in active (not too 
small that is not exactly computationally efficient;)
and that would replace also (part of) the grid/grouping desktop use case

also not sure about it, even tough applets without a frame are a quite rare 
and special case (and discouraged, i must add :p)

this will depend from the actual toolbox plugin (position for netbook toolbox 
has quite a different meaning for instance)
so the c++ part should probably export a writeConfig()/readConfig() there too?

are containmentactions plugins correctly loaded?

as far i seen, the items (not sure if they all do, or just mousearea) just eat 
the dropevent.
maybe the containment implementation in the scriptengine should 
filterChildEvents and catch drop events from there. not seeing many other ways 
around
