Thank you for opening a Pull Request!

Before submitting your PR, there are a few things you can do to make sure it goes smoothly:

• Make sure to open a GitHub issue as a bug/feature request before writing your code! That way we can discuss the change, evaluate designs, and agree on the general idea
• Ensure the tests are added/updated (if necessary)
• Ensure the linter passes (./codeAnalysis to automatically apply formatting/linting)
• Appropriate docs were updated (if necessary)
• This change has no user-visible / UI effect (refactor, docs, CI, etc.), so screenshots are not applicable.
