Possibly adding storage of hidden selections

According to Jonathan this is very hard to do.
Nevertheless it would be very helpful if this was fixed. Please consider fixing this bug for one of the next intermediate releases like 2.4.1 or so.
With a Mozilla xul tree, keeping track of what nodes are expanded is something that the nsITreeView has to do. (A nsITreeView is similar to a GtkTreeModel.) This may make this easier to implement. (Just a guess - I not very familiar with the gtk code.)
