Actually, I prefer the Side Bar to the left coz it shifts the main letter keys to the right. Ideally, since the letter-keys are tapped most often, they should be near to the right side for a right-handed person like me. Also, if the letter-keys are closer to the left, I'll have to position my right hand closer to the left, which blocks more of the bottom of the screen & the right side of the keyboard.
I enabled Events warning & it worked! :) I'll only enable it for the DP Test though; I don't like having those system noises otherwise. ;)
