Feature Request: "Break Line Here"

[Pistonight]

I need to insert a segment into an existing line, and currently I have to use the edit line mode to insert points and drag them accordingly.

It would be nice to be able to delete a point in the middle of the line, that breaks the line into 2 lines

It could be a new button in the draw control between "edit" and "delete", and when you click on a point it breaks the line
