Save button is confusing

Kids tend to see both the 'Download' and the 'Save' button and wonder which one they should use (and adults tend to be even more confused)

I think it would be good to be more explicit about the difference and make the 'save' feature to generate a python file slightly less on the 'fast path'. Here's a super-quick mockup to show intent.


Start by locating the editor's Download and Save controls and compare their current labels and placement with the linked mockup. Done means the distinction is explicit for children and adults, and generating a Python file through Save is no longer on the fast path.
