I just noticed that it is difficult to find specific lists.
For example: I just wanted to check if anyone made a list of best halloween horrors since its so close to Halloween. But had no luck in finding any, which is a shame, for the people who want to find them and for the people who already made such content.
So it would be great if this could become a feature. If the search engine could track the words in the titles of the custom lists, than with just words like "horror" you should be able to find lists related to this.
