First of all, let me start of with how much I loved the unified Horizontal and Vertical Constraint. However I would like to request an additional enhancement to it.
Right now we have the midpoint constraint but it can't do what I want to do as I described below and I feel the Horizontal Vertical Constraint will work better here.

As in the image above, I can't align the 2 points to the center of the top line, unless I manually dimension them to be in the middle.
Thanks
