Two biggest GUI hates?
Check boxes that are unlabelled slide switches or flat buttons. For extra hate make them monochrome outlines with only O position to indicate state. also Buttons or labels as check boxes that don't label CURRENT state but state if tapped/clicked.
Modal windows with NO back, OK, Cancel or X, apparently you tap or click on the background. Who hired the idiots that decided on this.
For a while I thought Win 10 (binary for two?) was the worst since Windows 2.0 on Hercules or Hires CGA (basically also only 1 bit but less dots). But Android seems worse.
