OK, it took awhile but here's a link to a JPEG that shows how we need the leaf node images to appear within a treeview:
Notice the position of the "green flags" in the JPEG. Currently, when we add a green flag to a leaf node, it shows up in within the text of the leaf node. For instance, “Bibliographic” is partially obscured by a green flag (something like “Bi[ ]ographic, where [ ] indicates the position of the green flag). That is why we want to be able to move the green flags to the left about 50 px. Hope this is clear.
