The default chaining option is now called "Natural", while the new chaining options are "Sketchy: Topology Preserved" and "Sketchy: Topology broken". The latter two options allow for generating chains of feature edges with a sketchy multiple touch. The "Sketchy: Topology Preserved" option takes account of the topology of objects in the view map, while the "Sketchy: Topology broken" ignores the edge topology. The "rounds" option specifies the number of rounds in sketchy strokes.
