For there words -- would it be possible in the functionality of the software to incorporate two different font colors that could be used to hightlight irregular spellings? For example the word "said" is not spelled like it sounds. So "s" and "d" could be spelled in black and the "ai" could be changed to red like this "said". That is a very basic example, but it would help with visual memory of medical terms that are irregular.
Whether or not it is possible -- you have created a tremendous app. Thank you.
