- The main block reserves the width and rows of its biggest layer, so the numpad and function row no longer shift between letters and symbols - Smaller layers stretch into the room: stretch keys widen, rows grow taller (rows above the layer, like the function row, keep their height) Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
