Checklist

• If a new package was added, did you ensure it works for all supported platforms? Is the package also well maintained?
• Did you add localization for any text? If yes, did you sort the .arb file using arb_utils sort <INPUT_FILE>?
• Check that any changes are related to the issue at hand.

Going forward, I won't be creating any more PRs for people unless specifically asked. I think it's selfish to take the merit from people who genuinely want to contribute.
