I've tried a quick and dirty prototype that computes the delta between the desired direction's reference angle and the angle between the currently focused element's centroid and the candidate element's centroid with an arctangent2, and it seems to improve performance a bit. @jihyerish knows how the strawman algorithm works, but the weights and magnitude have to be scaled to match the other ABCD scores in the distance computation phase.

Whether or not you factor this in is entirely up to you, but it seems to help.
