Left alphabet and shift same as right side but triggered by left swyping

When I use a right thumb the letters avoid the thumb even if it shifts left or right when swiping. However when I do with my left hand the letters are still and the opposite side and don't have that good feel. Also the alphabet should sick on the side it was activated from until the activation is switched. Also it would be nice if the left aligned menu avoided the thumb as well wether it's activated by left or right side
