It has a great idea but there are too many shortcomings to make it work for me. If your shortcut is the same as the last few letters in a word youre typing, it will expand it onto the end of the word you typed, leaving you with a jumble of letters. It also doesnt always format the beginning and ending spaces when it does expand it. Itd work great if these nuances were fixed.
