Media Managing/Photos

The media editing is horrible!!! Not user friendly at all, and taking up so much of my time to do something that should be so fast and simple. Very inefficient.

It keeps not saving/exporting the photos that I upload. When I move the photos around in a certain order, it keeps changing the order, EVERY TIME I save. I am doing repeated work over and over only to have a different result each time. Please update this to a more user friendly/efficient editing platform. So bad.
