Apps Organizer lets you label apps and then create a folder for that label. The folders function native to the Droid only creates the folder, and then you have to one by one move in the applications that you want, or the bookmarks, etc.
So, with Apps Organizer. you can make as many labels as you want folders, and not have to spend hours moving applications into them. You simply remove the folder, and you're done.
Additionally, for bookmarks from the browser, there's another application called Live Bookmarks that works well for me.
