Ok, here's a simple plan that should work: subtree_changed_tnodes = set() - When a tree-changing operation happens, we add the tnode of the parent (subtree of which needs to be created) to the set - Then, it's just a matter of maintaining a dict that maps tnode to list of positions (all clones), iterating though subtree_changed_tnodes and using the dict to re-create the dirty subtrees, skipping invalid positions. -- Ville M.
