*Follow Spanish grammar rules:
 -Only uppercase at the beginning of the phrase and names.
 -Less is more
 -/Settings == Settings/ and not /Settings == Configuration/;
  a bunch of better contextualized words are there for using them.
 -Don't _ever_ say please, golden rule.
*Add arrows to clarify page navigation with minimum space.
*Use correct nomenclature for technical terms;
 leaving them understandable for the power user.
 -Never, ever translate for the sake of translating, menus have to be usable.
