  ### Merge Requests

  # Merge Request Prototype
  # Title:
  # URL:
  # Type:
  # Status:
  # Comment:
  # git cherry-pick -n first_commit^..last_commit
  #
  # Possible Type:
  #   1. Improvement: Makes an already existing feature behave better, more efficiently/reliably.
  #   2. Feature: Adds a new functionality.
  #   3. Fix: Regression/bug fix only available in master (not backported).
  #   4. Cleanup: Code styling improvement, function deprecation, rearrangement...
  #
  # Possible Status:
  #   1. Needs rebase: Conflicts with master branch.
  #   2. Needs review: Mutter maintainers needs to review the new/updated MR and provide feedback.
  #   3. Needs changes: MR needs to be adjusted based on maintainers feedback.
  #   4. Merged: MR approved and it changes commited to master.
  #
  # Generally, a MR status oscillate between 2 and 3 and then becomes 4.
