Thanks for the PR! However, there are some things that need fixing about it. We encourage you to read CONTRIBUTING.md which gives instructions on how to make a good pull request. Looking at the format of other pull requests on the repository should help too. In particular, remember:

• Your PR title will appear in the changelog: make sure it's a good, short description of what your PR does.
• If it fixes an issue, use standard GitHub syntax ("fixes [link to issue]") in the description (not in the title).
• Visual changes needs before and after screenshots.
• Your PR needs DCO signoff. Checking the check box is not sufficient.

We'd welcome a new PR after fixing these issues.
