Currently, you can hide a show from you calendar or progress page. Hiding from watched progress also hides it from your dashboard on deck. Hiding in those 2 places should work for most users.
This topic proposes a “dropped” status for a show. This would hide from the 3 sections mentioned above + add a “dropped” indicator in places such as the show summary page.Lou Semin commented
I have a movie box that I have my tv shows listed through Trakt which is either listed in collection or favorite which is great until I want to delete them from my TV. Why is it so difficult to have an icon that when you click on it it will save to your favorites, then if you click on it again it removes from favorites. I can't believe it can be that hard to do. I never watch shows on the computer or iphone only on the TV.
