I try to keep (and constantly seed) every past download, and when I need to move a shared file, I'm careful to use Tixati to Move it so that it doesn't lose track of the file and continues to be shared.

Because of this, my list of past downloads is getting quite long. It would be incredibly helpful if there was a way to sort past downloads into "groups" so my on-screen list of files I'm sharing isn't a mile long. :)

Categories are for that, see in the help section.
