Terrible interface change

What did you do with interface? Left/right bar under left/right finger was the best and fastest way to navigate for left/right handed users. You changed that to bottom of the screen. I bougt your app because of simple interface and You ruined that in new patch. Now every time user change pages he/she has to move hand from side to bottom of ipad ?
Just give us an option to change interface bar to right /left of the screen because no one have third hand to use it Please
