I think this is an excellent idea. Especially the action triggering part. This 
might actually turn out to be pretty intuitive. Empty collections should 
always be collapsed and contain a text that invites the user to click it in 
order to populate it.
What action is triggered would then by defined by the kind of collection.

This could also be the solution for the problem with empty SQL collections 
Jeff mentioned in the release plan thread:
They would display a text like "Click here to add folders to your collection" 
and when clicked open a dialog to select collection folders.

So we should establish that as a standard behavior for any collection: When it 
is empty, collapse it and invite the user to initiate an action to populate 
it. Whether that action is simply activating a network scanner or selecting a 
local folder to scan then depends on the collection type.
