Optional suggestions

Every comment with the [OPTIONAL] prefix won't stop the approval of this PR. However, I strongly recommend you to take them into account as they can make your code better. Some of them were simply missed by the previous reviewer and addressing them will really improve your application.

Cheers and Happy coding!
