LOL. It is a new feature within the last week or so yes. As you may have noticed, however, the main video area's frame rate is cut in half as long as a clip preview animation is active. This isn't a big deal if you are focusing on the clip preview, but if your mouse is "accidentally" hovering over a clip that you are not looking at then the frame rate loss is very noticeable. In one of the next patches, I will make the animation only loop perhaps 3 times before stopping. There will also be an option to disable the clip preview animation entirely.
