Check-in list problem in mobile app

Check-in list has problems in mobile app. You have to solve it in future upgrades: - Check-in list titles can't be deleted, neither from title file page nor from Check-in list page - It is not possible to see if title is already added in Check-in list from title file page - I think it is not possible to search title by name within Check-in list - Also it would be nice to edit added date in Check-in titles. It is a very useful feature in a list that is suposed to be used for adding whatched titles in the past... Theese functionalities are implemented both in created lists (app and web) and in website mode. So it has to be added in mobile app. Thank you
