Describe the problem you are having and steps to reproduce if available
The sorting by Not-Watched Count has always been useless to me. It takes into account ALL unwatched episodes, even those that haven't been obtained or downloaded. The consequence of this is that if I sort by this method and pick a particular series, I may find that it's a mere placeholder with no watchable episodes at all.

This feature needs to be modified so that its action truly reflects the intent behind it: to decide what series to watch right now. If the series corpus includes any series for which all the episodes have not already been obtained, then this sorting method will not perform as intended.

What should be happening with this sorting method:

1. any series for which all the known episodes are not downloaded should sort to the very bottom;
2. any series which has a mixture of both downloaded and not-downloaded episodes that are unwatched should only use the downloaded count to determine where it sorts in the list and what value should be displayed.

Optionally, the displayed unwatched count could be appended with a parenthetical value that represents the not-downloaded unwatched count, as a quick and handy method of seeing which series need more attention.

Hopefully someone will eventually comment on the suggestion so that it can evolve to suit everyone and become a useful feature?
