Ideas and To-dos:

Current word list from 3-letter word list of valid Scrabble words. One issue with using Scrabble dictionary words is that many of the words are somewhat unexpected to casual players (e.g. MHO) and many are not even listed in Merriam-Webster (e.g. AAL & ZZZ). In case you were wondering, "Zen," in spite of its typical use in American English, is considered a proper noun, and therefore serious Scrabble players exclude it.
