The layout was set to the left side of the ordinary keyboard so that no more problem of reaching the shift key for capital letter. The finger could rest on home row with middle finger touching the pivotal key at the qwerty-f button.
The layout occupy four row including 1-6 so that all alphabet typing will not swing the whole hand over the standard keyboard.
However, I believe that the Fitaly layout is not optimised as some frequent letter such as H is placed on the top row making typing TH unnatural. I sincerely ask for your expertise for dumping the layout such as pkl for real testing and develop more alternative layout for people to choose from.
