Greatest Music App !!!! Just One Thing

I love this game so much because I can choose from a lot of Instruments. I love to play the piano the most and this is where I want to ask you guys a few favors. Is it any way you guys can make a "Dual Row Mode" for the Piano ? because I want to play songs like Für Elise, Chopsticks, Super Mario Underwater Theme Song, and songs that require to play some high notes and low notes at the same time. Also I would like for you guys to put every single instrument you guys know from all around the world, for example: the Accordion, Bagpipe, Ukulele, etc. That would really make me really happy and I hope it makes the mayority of people happy as well. Please and Thanks for reading this review ✋
