Description
Would it be possible to make Cura start layers along the path of a previous layer, so that it wouldn't try to start printing in air on a new layer?
Here's an image showing support structure generated by Cura, where a new layer is started in a way that the line will form a "worm" inside the support structure instead of it actually supporting the overhang of the real object, because when unretracting, the plastic is not always coming out immediately, but with a slight (a millimeter, perhaps) delay. Depending on a situation, this can also happen to the objects being printed.

Research direction
Start by reproducing the described layer-start behavior in CuraEngine and trace the G-code generation path that chooses where a new layer begins. Done means a new layer can start along the path of a previously placed line, avoiding unsupported starts in the support structure or printed object.
