Boomerang needs better features

IG needs to make it so that youre able to take videos already in your library and make them into boomerangs. I downloaded this just so I can take a video and make it into a boomerang because IG wont let me post it since its too short just to find out that this is not a feature readily offered by Boomerang. Waste of time to download.
