♦ About:
Changes the selection highlight because you don't like the
blinking highlight when selecting enemy or actor. Or at least
you want to customize its duration or the blend color strength

♦ Options:
Selection highlight comes from 3 options
- Blink (default)
- Flash 
- Whiten (persistent highlight)

♦ Terms of Use:
- https://github.com/theoallen/RMMZ/blob/master/README.md
