Very useful app! (with room for improvement)

It is a very useful and must-have app in Thailand. Thanks to the LINEs great developer teams. What I would hope to see is that the app has a DELETE button which users can select to delete unnecessary photos (along with the existing SAVE button). This button would significantly help to increase space in userss device without the need to delete all chat records (in any particular groups/friends if user do not wish to do so)
