Help me use Step in class

Hello everyone.
I am Baltasar Ortega, a high school science teacher.
I have used the Step application to explain physics concepts such as 
Uniform Rectilinear Motion or Uniformly Accelerated Rectilinear Motion.
The result has been more than satisfactory, both in academic results and 
in student motivation.

Nevertheless, I think that the project is somewhat dead, which is a real 
pity because Step has an enormous didactic potential.

I'm not a programmer so I can't do much for Step, so I launch an appeal 
for someone to revive this application.

Among the things needed, and perhaps the most pressing, would be a 
Windows version and the ability to save sceneries without messing 
everything up.

Thank you very much for your time.

Best regards,
Baltasar Ortega
