Wish this app had reverse tool.

I like this app. Giving it 4 stars. Easy to use. It has tutorial but I didnt view it. I just played around with it and was able to figure it out. Im a picture junky now. Not even playing Candy Crush anymore, because of iMovies. I am entertaining myself plus my family and friends.
I have made some funny movies, but wish it had reverse clip tool. Some videos just need to be reversed for a good laugh.
Please update this app with reverse clip. Please
Thank you.
