New to Trakt - help with collections and lists

Hey all,

I am new to trakt, having found it via search recommendations for a way to keep track of lists and my physical media/plex collections.

My use case is pretty simple, but as an example…

Fangoria magazine put out a list of 101 best horror movies list. Great!

A trakt user already created a list: Trakt Web: Track Your Shows & Movies. Also excellent.

I want to track my personal media discs ripped and to be ripped I order to see if I have them all. Hoping to generate that via collections and plex sync.

Darndest thing is, I can’t tell what I am missing or have via the list clones.

Does this make sense? How can I get this to work? Am I missing something?

Seems like a “owned” drop down in the filter would solve this. No clue how easy that would be to implement however.
