Developer Pull Request Checklist

To submit a pull request for review add the tag "PR-needs-review" to the request (and remove "PR-needs-work" if it is there).

In general (barring edge cases), PRs should meet the following before submitting for review:

• No debugging console.log messages.
• Any code you're introducing is actually used.
• Non-obvious code has some sort of comments, so it's possible for somebody else to understand the code.
• A list of exact steps on how you tested.
• Screenshots if relevant.
