Simple BitMask is the ideal way for managing enum bitmask values.

You previously had to write out a CustomEditor to be able to select multiple values for your bitmask.

With the addition of PropertyDrawers you no longer have to write custom editors. Simple BitMask makes use of PropertyDrawers by allowing you to use Simple BitMask in any script with 1 line of code. Simple BitMask provides the easiest method for allowing you to select multiple values from your enum type.
