Unfold causing some odd mappings/need for better manual controls

[Sailsman63]

I've found that sometimes the unfolder code makes some... odd... choices.

The selected mapping point is mapped to three different vertices around the edge of the face. This face has a total of 16 edges. (The outside of the box has a higher resolution than the inside)

I have not delved into the unwrapping code yet, but it would be nice if it would not do this.

Worse, there seems to be no way to select only one of the vertices at a time, and fix them manually.
