WHAT'S CHANGED: • Drawing engine now powered by Metal GPU • Completely modernized architecture • Hidden layers are now protected from accidental edits • Smoother, more responsive layer controls NEW FEATURES Metal-Powered Canvas Your strokes now render through Apple's Metal framework—drawing feels instant, even on larger canvases. No more lag when you're in the zone. Hidden Layer Protection Ever accidentally drew on a hidden layer and lost work? SpriteFrame now blocks edits on invisible layers and shows a clear warning. Your workflow, protected. IMPROVEMENTS • Rebuilt codebase following Apple's latest standards for long-term stability • Layer visibility toggles respond immediately—no more delays • Overall performance boost across the entire app BUG FIXES • Undo/Redo now works correctly in all scenarios • Export panel appears on first tap (no more double-tapping) This update represents months of work rebuilding SpriteFrame to be faster and more reliable.
