+When `true`, short hand props must be listed before all other props, but still respecting the alphabetical order:

 ## When not to use
 
 This rule is a formatting preference and not following it won't negatively affect the quality of your code. If alphabetizing props isn't a part of your coding standards, then you can leave this rule off.
