What's New

New features:
* You can now enter an equation by text - no more adding and editing individual formulae!
* As you type the equation, suggestions for possible formulae are shown - tap on one to complete the formula under cursor!
* Tap on the 'Clear' button to delete the formula / equation - no need to hold down backspace!

Enhancements:
* Input suggestions that start with the current formula are now moved up to the top
* Input suggestions that begin with a '(' or a '[' are now moved to the bottom
* 'Done' buttons are now renamed to 'Apply changes'
* The info button icons are now changed to zoom in icons
* The 'clear' button (looking like a 'x') are now replaced by to '0'

- relative atomic mass
- electronegativity
- electron configuration (abbreviated, box and arrow)
- common oxidation states and ions
* Chemical formula
- name(s)
- relative formula mass
- empirical formula
- percentage by mass of the constituent atoms
- oxidation states of the constituent atoms
- bond type
- mass / mole calculations
- ideal gas calculations (PV = nRT)
* Chemical equation
- equation balancer (redox reactions are supported)
