These are suggestions based on how my sites are set up and how I do things. Basically, ways to make things easier for me. :)
A quick visual way to see what the "view level" of a page. Publicly Visible/Logged In/Admin Only are the 3 I'd be interested in having at a quick glance. My quick thoughts on a type of display would be a outline around the text, green, none/black, and red. My site is mostly logged in pages, so that's why I suggested a border around the public pages, but it kinda makes more sense to border the pages requiring authentication.
Another setting displayed that would be nice for me, would be to see if a page isn't displayed in in the menu. A quick thought on the display for this is a different folder icon.
Other than being greedy and wanting more information, hehe, I like the module.
Playing around with the drag and drop I noticed (and find it very nice) that the little arrow flips between being on the folder, indicating the same level, and being on the name, indicating to go as a sub page. Took me a few minutes playing around to figure out it did that. :)
