Having to press the button for each individual image resize or having to use the shift hold hotkey is inefficient. It would probably take less than an hour to code, and I am sure plenty of people will enjoy the quality of life upgrade.
It would seem like with the amount of resizing people do, this would be a "no-brainer", but apparently I am mistaken.
