anyone know of an app for organizing map bookmarks. I want to add bookmarks, label them organize them by groups and write a description and maybe link them to a picture and have them show up on the map. then I could make groups like restaurants i know or want to check out, bars i like or want to check out. interesting places. then when i am in the neighborhood i can pull up the map and see what is around me, organized by the bookmarks I'm interested in.
