Yeah that is a big feature I would like as well! I'm not sure how that would look however, how would you like to see it? When you see a movie in a different library you don't have, should it have a green glowing border if its new and a yellow border if this is a higher quality one? Or a filter which only shows new or higher quality movies? Or everything on a different page?

I'm also planning to make the home page which now says "Working" a collection of all Media over all the different servers so you can just keep scrolling on 1 page to see everything.

Anyway please let me know if you have ideas!

Maybe a "Missing" tag and a "Higher Quality" tag. Another thing that would help would be to put sort the movies in the same order as plex. For instance, the movie "A Beautiful Day in the Neighborhood" sorts at the top of the A's in PlexRipper, but sorts after "Bea" movies in the B section in Plex. Makes it difficult to compare libraries.

I've added this as a goal for release v0.11, other things take some priority but I'm still a huge fan of this idea!

just figured i would jump in and say that this would be an awesome option to have and for someone like me an additional option to grab all that is not on my server would be great
