Amazing but could be better

This app is one of my favorites! But can you add more special effects like allowed the video to be more fancy? Like making it spin, vibrate, change colors, move around a bit and ect? Also can you make it so that we can spit the audio and music? The music part gives me a bit of trouble cause it always goes to the middle of the video instead of where i want it. If you fix these then this app will be perfect!
