For quite a long time, I didn’t like the app icon of Amino Acids Structures and Names. It was too dark and the spacial formula was hard to comprehend that it is cysteine. So I decided to prepare this update with a new app icon (proline has three-letter abbreviation Pro) and some other improvements in design and localization. I can’t say that I’m completely satisfied with the resulting icon. The formula could be a bit larger, especially its labels. Maybe I’ll update Amino Acids again, but not now.
