I noticed that when I'm made joint owner/editor of a page, there is no way to find that page listed under my profile like the other objects I've created. Just for the sake of managing those pages and remembering which ones I have privileges for, it would be really nice to have an expandable profile section of "shared" objects or "co-owner" or "co-editor" objects.
Good idea, and maybe one Matt might be able to add.
Currently, you can go to "Objects I Can Edit" on your profile page and find that information, but if you have a lot of pages (as you do), it's not so convenient for finding pages you can edit but don't "own."
