@fabianoriccardi, I have spend some more time reviewing this PR. I like a lot of your improvements but you also included many changes based on personal preference, rather than necessity. Also, much of the added text contains grammatical errors. I am not interested in a complete overhaul or restyle of my applications. I think you should break this PR up into smaller PRs that focus on bug fixes rather than personal preference.
