If you use the same library with someone (like I do), it would be great if you could send that person an entry and that person could import it within the app. For example, if you create an event list and you would like that event to appear in someone else's event list it would be great if you could simply send that entry by e-mail, etc. This could be as a text file (like you share entries now; this way you only have to create an import routine) or in a native format. I think this would increase the use of the app since it's easier to share things and let other people try it out.
