Hi Burr yeah there needs to be a way to adjust the seam manually to help out for cases like this. Probably some stuff like an "Edit seam" button can go on a detailed object properties dialog where I can jam in a whole bunch of special edit tools.

For the more regularly used tools like Loft I've tried to set it up so that you don't have to worry about seams since it will relocate them automatically but other tools especially kind of "quick and dirty" plugins will probably need them adjusted manually.
