With the latest U test patches, you can do camera rolling also.
Just make sure that you have settings like smoothing and such to a value that is not so slow or so fast.
Some keys you use for this camera/editing mode are:
V - Raise/Lower view angle 5, 6 - Zoom In/Out CTRL+ up/down - Raise/lower camera height CTRL+ left/right - Roll camera left/right O - place an object 1 - Checkpoint 1 2 - Checkpoint 2 3 - Checkpoint 3 S - Place start position F - Place finish line
looks like it's already released... though from the screenshots I got the idea you have to use LFS windowed mode when you're using that utility which would suck.
