Input Checks

 
Any data input under an object type automatically initiates input check mode:
 

Valid input is indicated by a field turning green after editing. Following confirmation of the input, the field turns white.
 

Invalid input is indicated by a field turning red after editing. Following confirmation of the input, the field remains red. Any invalid input is not saved.
