@jmclaus Hey Jean-Michel - I can't get this to work. When I create the component in my toy course, there's just a big blank box where the molecule should be. Can you look through this and let me know if some of the instructions are wrong? Thanks!
These are two separate items, but they both use JSmol (a JavaScript-based molecular viewer).

With the molecule viewer tool, the instructor creates an image of a molecule for students to look at. That's the MoleculeViewer.png image above.

With the molecule editor exercise, students build molecules themselves. (See the Molecule_Editor.png image above.) Yep, it should be a problem rather than a tool - thanks for the catch!

I know it's confusing - the original ticket had me a bit mentally turned around at first...
