I figured I would need a separate glist, I can get the last know order from the order of the original glist.
When I get the reorder signal it appears to be run after the reorder event has taken place. So I see the need for a unique id. I assume this is where g_object_set_data comes in? How would I use such an id system though? Also sorry if this top posts its being composed on my phone, I don't know how it copes yet.
