when working on my dissertation project with Bookends, (smart) groups become more and more important. A problem when working with many groups is organization: In iTunes, this is a lot easier with folders, where groups can be organized and sub-grouped. Wouldn't this be a useful feature for bookends as well? This would make it easier to have project-related sub-groups, an extremely handy feature if you have to create literature lists in different contexts: for coursework, for others, for your ph.d. project or for every chapter. What do you think?
