Two related and very useful features I'd suggest:
1. The ability to see how many unwatched episodes you have for a paticular TV show. Having a general unwatched indicator is nice, but it's very handy to be able to see the total number. It displays the number on the web version on the server, but not in PHT. A simple option to turn this number on or off through the settings would be great.
2. The ability to be able to sort by said number. So, if I have 5 unwatched "Workaholics" episodes, and 3 unwatched "Big Bang Theory" episodes, selecting "Unwatched" under the sort section on the left would put "Workaholics" first, then "Big Bang Theory", then all the rest of the shows in alpabetical order. This allows you to sort by what you still need to watch, without filtering out all the others (less clicking around to find what you want).
