Feature Request: Adding intersecting line should split the initial line / Trim tool

Description

In Eagle, when intersecting an existing dimension line with another line end point, it splits the initial line at that point, so you can trim or move that section.

In KiCAD if I do the same thing, I then have to either delete the initial line and re-make it, or move it and re-join the line points to the new locations.

This makes modifying board outlines (or even silkscreen lines) really difficult and fiddly. It would be great if KiCAD could implement this same behaviour for all "line work" (lines, arcs, squares) for al layer types that support them :)

Example from Eagle!
