AuraCanvas

There's a new eraser tool tucked into the bottom toolbar. Tap it to start erasing, and long-press it to set your eraser size with a live preview. Whatever you erase is honored everywhere, including when you export as an image or a Living Canvas video, and it cleanly reveals whatever background or reaction art is underneath instead of leaving a blank patch. Speaking of exports, you can now save your artwork as a transparent PNG. Just flip the Transparent toggle in the Export sheet and your strokes float on their own, ready to drop into other applications without dragging along a black rectangle. The Reaction style got a major glow-up. Six named patterns (Mitosis, Coral, Spots, Worms, Fingerprints, and U-Skate) are now selectable from its long-press card, each producing wildly different diffusion art from the same canvas. Reaction now spreads across the whole canvas instead of small isolated bubbles, so you can paint continuous flowing patterns. Your selected preset sticks around between sessions, and your reaction art stays visible while you switch to other styles to layer brushwork on top. A few quality of life touches: app sounds can now be turned off in the Advanced panel for quiet drawing, undo goes back up to 30 strokes (15 on older devices), and the floating menu button stays visible whenever you are not actively drawing so you never have to swipe it back. Plus the usual round of layout polish and export fixes.
