Netflix recently rolled out the ability to take out titles you're no longer interested in watching. It's currently only available on Android, and it will be coming to iOS on June 29. There is a three-dot menu at the bottom of each title. At the bottom of the list, there's the "Remove From Row" option you can select to remove the title you want to take out from your list. There is no word yet when the feature will roll out to other platforms.
