My students often have trouble linking the heads and tails of arrows to rectangle corners and midpoints and arrow midpoints. Arrows often look like they are touching the points or corners when they're not. The only way to tell for sure that they aren't is to move the box or arrow. It would be nice if, when drawing an arrow, mousing near a rectangle corner or midpoint or an arrow midpoint would cause the former to "snap" and link to the latter.
