Yep, UI desing issues, i made the UI somewhat compact to fit in smartphone and did not find a way to put that many buttons. So not left them out on pourpose, but I had to make concessions, with the external rows and columns movements you can perform all the other movements i left out, it's more trickier but not impossible. Also the Randomize only uses that movements
