  • X
    button location inconvenient.
  • Hard to reach one handed.
  • Interference with edge (iPhone 13 & Pro).
  • Issues while Display Zoom on Larger Text.
  • Close
    is possibly the most frequently used action (Chose Color and Share/Shortcuts possibly less frequent).
  • X
    can be confused with “delete”; icon
    might be a better option.
