Polyline selection tool
Quick but really powerful polyline lasso
Just tap, tap, tap. Or draw like with the Lasso.
Tap to add a node (corner); drag to draw a freehand line.
Finish the shape.
If you tap and hold your stylus down for a second, you enter precision mode that allows you to drag the node to desired location. This works similar to Shape detection.

Drag to add a smooth node.
Tap to add a cusp (corner) node.
Tap on a node to toggle between cusp and smooth type.
Drag a node over another node to delete.
Close the path.
Finish the shape.
