Is this you? http://forum.timescapes.org/phpBB3/view … 687#p40687

Pasting from what I replied there:
I spent some time implementing timeline like features where you can add keyframes the and the motor will follow the curves positions over time. Its not completed yet though. So far the amount of feedback or demand for this software cycled between very low to non existent. To be honest you are the first person interested in it for some time
I was hoping for more people to get involved - after all its an open source project. My time is limited and because of the above I did not spend much time on the software recently.
