just saved me hours of work . I had x mirror on but it did not work i guess you have to work on the left not right side of model? the only symmetry option that work was selected bones though but it worked.
One of the best ways to do retopo. id like to make a suggestion though . For when using annotation to create topology to make the different annotation layers be used to create different parts of topology when clicking add surfaces button . as of now they either get ignored and erased if not selected. it just be nice to draw out the main loops like eyes mouth etc. and then hit ad surface and get all the loops in one click.
thank you this is great just tested it out on widgets create by rigify which are not great. definitely helps simplify the rigging work flow
