Action: Type “2.5in”
- What’s the user’s goal, and why?
- Their task is to change the width of the column, and there’s a “Width” field highlighted, so specifying the width is what they’ll try to do now.
- Is the action obviously available?
- The highlighted field should be fairly obvious. There aren’t many other options.
- Does the action or label match the goal?
- “Width” is a good match... but why “2.5”? And how will the user know not to type “in”?
- Is there good feedback?
- The number shows up, but its effect isn’t obvious (standard practice in Mac dialog boxes, of course).
