Now that I'm back from the holidays, all immediate issues are taken care of here at work, and iTunes Connect is back up, I've submitted version 1.3.1 of Molecules for review (and updated the source code. This is a bugfix version, addressing the recent crashes when trying to search the Protein Data Bank. The PDB servers stopped responding to one half of the search query I was sending, which was a condition I had not anticipated, and Molecules would crash as a result. Unfortunately, until they fix the server response, the search results will no longer list the titles of molecules.
I apologize for any problems this has caused. I was stupid not to anticipate this kind of response.
