For now, we can only browse custom lists through users' profiles or drama/film pages, but wouldn't it be cool if there was a separate sub-tab for Custom Lists under the Home tab?
This is Goodreads's Listopia:
In MDL's case, books would be replaced with dramas/films/actors and related stuff.
P.S. another cool feature that Goodreads has when it comes to custom lists is that other users can vote on the titles in them so the most voted books appear at the top. Not sure if this would make sense at MDL.
And of course, only public custom lists would appear.
