The "palette handle" is at the bottom right corner (as indicated). When you move the cursor over it, the shape will change, just click and drag when this happens.

The other features don't seem to have made it into the release.

Be sure to head over to the CL (e-Frontier America) website to download SR1 and the content updates.

You'll also want to visit Content paradise for other content updates and freebies (use your browser rather than P6).
