When drawing a line (A): To start, you click on an empty area, then you click somewhere else to get a line (A) between the two points. Then if you click on a point on a line (B), your line (A) share the same point as that one. Next time, maybe you want that your line (A) follow that line (B) and you click on that line (B) a few points away, then your line (A) will just have your clicks as points, but it would be great if this action could mean that your line gets all the points in the other line (B) added to itself so your line (A) will follow and share the same points as the old line (B).

This is useful if you are drawing a forrest into the coastline or a farm.
