"Hallon can create bookmarks in many applications (like iTunes) that usually can't create bookmarks and they are always accessible from a menu whatever you are doing. You can e.g. bookmark your favorite songs, an email that you have to reply to later that day, some documents that you are working on or the contact information of a friend whom you need to call before the end of the week. And you play the song, open the email, the document or the contact information just by choosing the bookmark in the Hallon menu. You create a bookmark by selecting what you want to bookmark and then press a user-definable hotkey or by choosing "Add..." in the Hallon menu. If you want, you can write notes and set a due date with alarm for each of the bookmarks. Hallon comes with support for Address Book, Finder, iPhoto 5, iTunes, Mail Safari and Terminal but you can yourself add support for many other applications by downloading from the site or creating your own." -text from the site
