Default App drawer, menu/Z-ultra port to Xperia Z

Hi people, I'm a xperia z user actually running .230 firmware 4.4.2 KK, in development forum there's a rom giving some ZU taste for our beloved XZ, based on KK but bringing a 7 app drawer like the attached picture below, it seems to be some kind of modded framework...(?), can u help me guys? i really want my drawer like this.
To clarify, my rom is fully stock deodexed.
