Neat but it looks like it is reinventing the Arabic QWERTY layout slightly differently. The QWERTY layout uses shift for the special letters here. So ش is shift+S. Another neat thing is it maps the transliteration alphabet as inspiration for letters that don’t exist in English. For example, ع, Which is informally “3ayn”, is on the “e” key right below the 3 key. I don’t know if the transliteration bit is intentional or a coincidence.
