This request is adding and extending feature in the Web UI. Right now, custom lists does not have filter option and sort by options has "Original Order", "Rating", "Release Date" and "Title" present. My request is the following:

1. Extend sort by options in custom list by adding "Runtime" option. For TV Show's runtime either total runtime including all seasons can be taken or TV Show's can be added after all the movies are listed when sort by runtime is used or they can be directly filtered via selection list of All, Movies only and TV Shows only as mentioned below.

2. Add new feature in custom list as filter by Genres where user can filter all Movies and TV Shows by one or more genres. This feature can also be added exactly as trakt.tv has, two selection list where first is for selection of All (default), Movies Only and TV Shows only and second list will have All Genres.

These two feature will be very useful for users who are maintaining larger lists and also want to select specific type of Movies/TV Shows.

Let me know if there is any confusion in understanding.
