When I hide a finished title, where does it go?

I don’t know if this feature has been implemented yet but I have noticed that in the Reading Now page, it only shows 3 comics under the Pick Up Where You Left Off and Finished Titles.

I’d like to see the all the comics I’ve finished. I noticed that if I hide a title, The comic I’ve read before that comes up.

I’d like to see this feature come up so that I could look back to the comics I’ve read. If such feature already existed, can anyone teach me how?
