Please fix the smart guide's line extension tool tip when moving points if you are zoomed in. It currently snaps to the opposite end of the line, meaning if you are zoomed in (which you almost have to be because the tool is so finnicky to get it to snap correctly), you have no idea if you are extending the line correctly. A good fix would be to put that dialog closer to the point, if not on the point you are dragging out to extend, vs. the opposite end of the line.
