I would like to make a suggestion, there are some people like me that have large fingers and its quite difficult to press the buttons sometimes. It would be neat to see that the buttons and texts can be enlarge and add "polyatomic ions" in reference. Please and thank you. This app is awesome, it just need to add some additional detail to it.
