Feature Description

Splits lines or regions using a drawn temporary split line.

The Line Split button becomes available only when there are editable layers with one or more selected objects in the current map.

When multi-layer editing is enabled, the drawn temporary split line will divide all selected lines or regions across editable layers that it intersects, which may belong to different layers.
