You could just drop the sentence since the top scoring words are shown below.

Other nits:

- Gray the submit button until the word is valid, otherwise it's unclear why clicking on the submit button doesn't do anything.

- If you are trying to find a word and switch tabs, things get reset when you come back.

- If you place tiles forming a word, a space, random tiles: you can submit the first set of letters. IMHO, it shouldn't let you submit if you have spaces between tiles.

- Display the best word I have found so far, but let me keep trying other tiles.
