Supports all operations with arcs.

Able to monitor clearance during rounding.

Separate menu items.

- "Select bad Smoothed Tracks" - Selects all tracks where the routing is poor.

- "Cleanup Tracks" - Cleans overlapping and damaged tracks. Removes debris stuck under pads.

You can add teardrop shapes to rectangular pads if they were selected with the mouse in advance. However, this feature is rather unreliable; all pads are treated as round.
