Feature Request: the ability to reverse the current animation

[tennisgent]

I am often using your tool to create "open" and "close" animations. I love the ease of use by the way. But it would be great to use your online editor to get the "open" animation just the way I want it, and then be able to push a button or something and generate the reverse "close" animation, which would be the exact same, but in the opposite direction. Do you think that would be possible?

My thinking as well. I tried to use: animation-direction: alternate; but that didn't seem to do anything.
