If you're willing to put some work into it, you could use the tag feature. Next to the genre, you have "no tag" written in green. You click it and you can edit the tag associated to the movie. For example you could tag "horror" all the movies that you truly consider as horror movies.
You'll be able to use the tag filter.
There's a keyboard shortcut to tag faster:https://www.coollector.com/help.html#shortcuts
would love to be able to pull up recently added movies though
I'm afraid I don't understand what you said. Could you elaborate?
The status filter has a "recently owned" value, and the rated filter has a "recently rated" value. Does it help?
