General Guidelines

• If introducing new functionality or modified behavior, are they backed by unit tests?
• Have all unit tests passed locally? (by running npm run test command)
• Have you updated the README.md with new screenshots if significant changes have been made?
• Have you update the package version if the current version in package.json is not higher than the version released?
