Reviewer, please remember our guidelines:

• Be humble in the language and feedback you give, ask don't tell.
• Consider using positive language as opposed to neutral when offering feedback. This is to avoid the negative bias that can occur with neutral language appearing negative.
• Offer suggestions on how to improve code e.g. simplification or expanding clarity.
• Ensure you give reasons for the changes you are proposing.

Hi. Looks good. One question: I see the icon you are building. Why are you building it instead of using something like fontawesome? (Just curious)

Thanks, Suzanne! I downloaded the SVG from FontAwesome and plugged it in here. It seemed easier to do that than have a dependency. Does that seem like the right way to go?
