Something that irritates me in desktop design is, there’s a clickable icon. There’s no box around it to represent a button, just the icon on a blank background. You move your mouse towards the icon. When you get close to the icon, a box appears around it. You take this to mean “this object will be interacted with when you click the mouse.” You click the mouse. Nothing is achieved. You have to move the mouse into the actual borders of the icon, it’s just that now icons get visibly excited that you might pick them.
