Since I like to type without looking I thought it would be neat to have some sort of overlay to kind of tell my fingers where they should be. I made one out of cardstock and it works sort of (the cardstock keeps slipping under the edge of my case).
I would love to have one made out of the rubbery material that my Apple IPad case is made of. Then it would just pop-in and be held in place.
Everyone seems so inventive on this board that I would throw this out for consideration.
