Standards checklist:

• The PR title is descriptive.
• The PR doesn't replicate another PR which is already open.
• The PR has self-explained commits history.

• The code is mine or it's from somewhere with an Apache-2.0 compatible license.
• The code is efficient, to the best of my ability, and does not waste computer resources.
• The code is stable and I have tested it myself, to the best of my abilities.
• If the code introduces new classes, methods, I provide a valid use case for all of them.
