PDB viewer enhancment

Brad, are there any plans to include some of the functions found in Swiss PDB viewer or similar applications? I am particularly interested in allowing my students to measure the distance between atoms. Obviously this would require an atom or amino acid labeling function, and a distance calculator. I am not a proficient programmer but would be interested in assisting with the development. I am currently using your app on Ipads in a Molecular Biology class at U. Cincinnati. It would be great to allow them to do a few more things with it.
