Couple more items

Here's a couple more things that come to mind as I play with it:

• Ability to zoom in on the timeline to manipulate keyframes with more precision

• Ability to type in and go to a specific frame number on the timeline

• Next frame/previous frame buttons on timeline

• Ability to turn objects visibilty on/off using keyframes (not just globally)

• Control over path of animation using bezier curves (this might be a crazy complex request...but figured I'd throw it out there) :)
