Knife tool is too difficult to use effectively

[Astiolo]

I think the knife tool should work more like it does in the regular version of blender. Were it uses a click to start, then a click for each segment. It should also preview where it would start and highlight any edges or vertices that would be selected before any click.

Currently it's too difficult to know where the cut would start and then it instantly makes a segment as soon as it reaches another edge. This means I find myself needing to be very careful and slow to try to get a cut that's even close to what I want. I certainly can't get it to go to/from any desired vertex.
