Atomic Table Inspector

This inspector allows you to change the default appearance of any atom. By selecting an atom, you can change its color or radius. Select "Update" to make any changes take effect.

There is also a global size ratio which will let you change the relative sizes of all of the atoms simultaneously. This factor is not saved and defaults to 1.3. In the quick rendering mode, a setting of 1.05 looks better. 

You can also save any changes you've made, or revert to the last saved settings. Setting are saved in ~/Library/MolViewer.dat
