Two versions are very useful. It is really clever that there is also a version without the diacritical marks. True, this is "wrong" Czech, but if you work from, say USA set computer, and write in ASCII to be sure about delivery to another computer, this is great help. Although I consider myself a good speller, I found a few mistakes I was consistently making. As seems to be the case with other Czech spellers using the diacritical marks, the hints for misspelled word often miss two similar words, differing by a diacritical mark. Also, a hint to replace "y" for "z" (flipped on the Czech keyboard) would be a nice feature.This review is for a previous version of the add-on (1.0.1).
