ALJUK Butler handles bookmarks differently to this app - it keeps them separated by browser, whereas this app aggregates them, orders them alphabetically, and opens them in your default browser as opposed to the browser in which the bookmark was set. Yes, Butler can be customised, but this app is far quicker and more useful "out of the box" for bookmark aggregation. And since Butler is soon to become a commercial app and newer versions will not be PPC compatible, AllBookmarks very much has its place. I am a big Butler fan, but AllBookmarks p***es all over it for bookmark aggregation.
