trying it right now, nice :) was trying to obtain the other way but it seems 
enabling the handles in the panel it's not possible to drag applets back to 
the desktop, seems like a mousereleasevent is lost somewhere :(

like it because it looks like it could be used in the future also for 
rearranging items in the panel
is addapplet() used somewhere else? i'd say keep it and make it private
or if your function could work with a geometry parameter instead of a position 
(would make applet with wrong sizes in the panel?) it could become the only 
one and the one that creates the applet simply creates it and calls the new 
function

note on
//FIXME assuming everything else behaves like desktop
maybe it would make sense a virtual hasFreeLayout() or something like that in 
the containments implementations?
