This is already done by Wikibase. There should be a "data item" link in the toolbox in the sidebar if the item is connected.
I have no idea how I missed that. Well that should save me some time. I was about to go make a gadget to replicate that functionality.
What would also be useful, would be a "create data item" link, if no item exists already.
/\ This! Agree completely.
Also is the norm for this list HTML or Text email?
