Suggestion to help planet motion demos

Asked by John Cotton

There are times when a planet motion demonstration would be MUCH more effective if daily motion could be suppressed while time runs. Let everything else move - just with no daily sky motion. You would position the sky as desired, turn off daily motion, then run time so planet motion over time can be clearly shown.

A flag variant (like flag daily_motion on/off) could control it.

This is what the sidereal time keys and related features are for. Also see, for example, the annual motion script.
