It would be extremely useful IMHO to automatically group the newly imported books so I know what is new. Ideally it would put it in a collection or assign a category keyword. I know there is a "just downloaded" collection, but that empties as soon as you switch applications. I would want it to stay there until I assign a different keyword or collection.
If this functionality already exists in some way, or there is an easier way to address it besides opening every new book I import and putting it into the "New" collection I've created until I have time to read it, please let me know! :-)
Thanks,
