OK, looks like I did get a good dictionary. First impression is it works just like it should
Basically you type and it underlines words that it thinks are wrong. Click anywhere on the word and you get a menu with possible correct spelling. There appears to be an option to add your own custom words (when you click on the underlined word "add word" is an option).
The only thing I can see missing on first (quick) glance is a bit more configuration options. I'd like to be able to tell it to skip all words in all caps (ala acronyms) etc.
Great job so far.
