Display a preview line (like the lines that show up when you grab and move a point) from the closest endpoint to the cursor. This will lower the unpredictability of which endpoint the pre-vis will draw to when the user clicks
It would also be nice if, when the user holds 'Ctr', the preview line goes away. This should only happen when the Ctr-Leftclick functionality to place a point without connecting to the closest endpoing is working.
