[Plugin: CMS Tree Page View] Doesn't reassign order, doesn't display in menu

After install into wordpress 3.1 I can click a link in the admin panel for display on dashbord (doesn’t seem to do anything) or in menu (allows a link to be displayed on admin menu under Pages). Using the second, I can make a view of all my pages appear in the center area of the screen, and I can drag and drop them to rearrange. However:
1). I wanted to see this listing in the admin menu, expandable, collapsible, so when editing a page I can quickly go back and forth between pages. This interface still has me doing too much clicking to switch editing pages.
2). When rearranging the pages in their hierarchy, the plug in doesn’t really change their display order. If I click to edit I can still see they are all set to zero (default). I need this changed so other plug ins will keep the same order.
3). No explanation for what the little exclamation points on some entries mean (at the left of the tree).
