I think it will be nice to have ability to create subcollections (or in other words - folders) to store items in different lists, like in many other programs. For example for me is useful to create separate list for coins for sell, my wishlist and so on. With ability for simple dragging of items into another subcollection (like in Windows Explorer).

Oh yes, Jim, I would love that too. This is exactly what I wrote in my request about [url=http://www.collectionstudio.com/en/forums/collection_studio_features/feature_request_lightboxes/]lighboxes[/url]. Maybe the admins could blend our requests in one, because I meant exactly the same thing like you.
