NEW: Stroke Opacity + Zoom / Pan
Stroke Opacity
You can set the stroke opacity for each tool now. This allows you to make really light fills that build up with each stroke. The opacity is set and remembered for each brush type. You can set the opacity under the brush color. Just click and drag left and right.
Zoom and Pan
You can zoom and pan now for detail drawing! Use your mouse scroll wheel to zoom in and out. If you hold shift and click and drag, you can pan around the image. You can also use Command/control + +, -, and 0 to zoom in, zoom out, and reset to 100%.
