Where are the “Thousands of grid designs?"

I can only find two: modern and old fashioned, and I don’t like either of them. On my iPad, I have a sudoko app by Finger arts. It has lots of grid designs, so you can find the least distracting one. However the feature I REALLY like, that this one does NOT have, is that when you are filling in any given number, say a 2, it highlights all the other 2’s in the puzzle that are already filled in. This helps the game go faster, without having to use the “help” button. I wouldn’t have bought this if I could have seen it ahead of time. I bought it because of the reviews, and the description, which clearly states there are “Thousands of grid designs. There are not.
