Re: this option in the overflow menu in ACP > Manage > Categories

Thoughts:

• Help text is recommended in this modal to explain that:
  • Specifying the index bumps the categories below it down the "order" chain
  • The order is 1-indexed
• Use <input type="number" min="1" /> instead

As an aside, it seemed to me that when I first entered the page, all the categories had their order set to 0. Not sure why that was the case, but it works fine now.
