Fun to use, but limited application

Fun to add some movement to messages, but this apps use would definitely be improved with a countdown timer (duh! Why is this not already a feature?), and would get even more usability if existing videos could be inserted into it. And what if it somehow worked to loop Apples already existing Live Photos? Now that would be great!
