Dear Bob,

The biomolecule filter is extremely useful, and I think you've touched on a very important issue here.

I understand that selecting different atom groups generated by the symmetry operations is done by using "select symop=X".

This is very nice.  Is there a way to return how many symmetry groups exist in the currently displayed biomolecule?  Something like getProperty("modelInfo","currentSymopCount")?

Some natural extensions to improve the useability of the biomolecule feature I would suggest (and would absolutely love to use) are the following:

1.) hover reports could specify %S (or some value not yet used) to show the symmetry operation number.  
2.) setPicking symop  -- when the user clicks on an atom, all other atoms in that symop are selected

What do you think?

Thanks again for adding such a useful feature.

Best regards,
