Overview

• focussing on middle dot, left characters are recognizable easily but not right ones
  • bcz, over time we have trained ourselves to read from left

• upper box looks longer length wise, though they are same in size and symmetrical to center

• upper ui is poorly designed, lower is btr

• scroll bar ko left me daal de toh btr = balanced
