I really wish they would bring back the unused word "por", but it better not be a sentence only word, all those need to stop being sentence only words. Not only do the letters "á" "é" "í" "ó" and "ú" need their own sections for words like "árbol" and "él" although they aren't considered seperate letters from "a" "e" "i" "o" and "u", but they should try to find more words, especially those with "k" "w" and "x", as well as finding Spanish words with "ü" like "pingüino". I'm not asking for place names like "México" for words with "x" though. Oh, and I looked it up on Wikipedia, and "ý" does exist in Spanish, it's just only used in a couple of names.
