YES.... and make bulk saving easier by allowing pdf saving of urls for each group and the total page of all urls in all groups. I like to file my individual groups by bookmarks subjects... like - computer, vehicles, military, food, history, movies, books, maps, weather, completed purchases, product searches, repairs, how to, people, etc. Your groups together or separate, will not save the urls in pdfs, by group nor by total url's. Pdf's are easier to quick pop-up in a tab, to use online. And they can be opened by programs and recombined in to groups.
