This keyboard has potential but has the same bugs the stock keyboard and other ones have. In the Android email app when you add or edit a word in the middle of an existing sentence it capitalizes the first letter of the word, even if the word is in the middle of the sentence. It doesn't do this in text app or web forms. Also, in the email app when double spacing the keyboard starts deleting the last word in the sentence after a few "double spacing" attempts.
