Modelers want an option to ignore any UVs that are flipped while running an Unfold or UV Layout operation using Unfold3D technology.
"Add an option to ignore flipped UV shells or rather keep their current orientation when unfolding UVs.
Would help a lot with symmetrical object that have mirrored UVs and require adjusting their UVs after they have been added."
