A quick guide
Bucket Fill can color any empty grid section immediately. Turn off Repeat Fill Around Ring to color just the clicked region. Drawing tools always repeat independently.
To draw, choose Select Ring and click a ring, then pick Black Pen, Line, or Color Marker. Black grid lines always stay above the colors.
Use the mouse wheel to zoom around the pointer. Hold Space and drag, or drag with the middle mouse button, to pan. On a touchscreen, use two fingers to pinch and pan together.
One finger or a stylus draws. Escape cancels a stroke. Your artwork saves locally; exports always include the full mandala and creator credit.
