My situation: I have laptop which is 16:10 & my desktop is 16:9 When position itemrack button on the right side of screen, when I switch my game from 16:9 to 16:10, the button just go out of screen. It would be better to check the button position and apply archor point to LEFT,RIGHT,TOP,BOTTOM of the screen accordingly.
