Numbered lists are used when the items must be performed in sequence.
I'd rather see bullet lists in place of numbered lists.
Just a matter of taste maybe
Here's a list of Unicode bullets.
Some of them won't display in every font.
The ★ is pretty safe I think bc CM uses it at the bottom of the page.
★ ★ ★
⭐ Gold star

I got some of these from Twitter so I think they are in common use in the most widely-installed standard Unicode fonts.
I have a lot more but some of them are ghey.
