Redesigning a Mobile Toolbar Under Fitts's and Hick's Laws

A mobile app's editing screen has a toolbar of 14 icon buttons in a single horizontal row along the top of the screen, each about 24x24 points, packed edge-to-edge with 2px gaps. Below the toolbar is the main canvas. Users on a usability panel report frequent mis-taps and say the toolbar feels "overwhelming" even though they only regularly use 3 of the 14 tools.

1. Diagnose the two distinct problems here, naming the specific law each one violates.
2. Propose a redesign that addresses both, being specific about layout, not just "make it simpler."
3. What's the risk of over-correcting your fix, and how would you guard against it?
