1) While holding shift in Quad Draw mode to relax my geometry, I can't see the falloff diameter of the relax brush so it's difficult to be precise with it. I would like to be able to see and adjust the diameter and strength of the Quad Draw relax brush.
2) The Auto-Lock options for the Quad Draw Relax brush are great, but what would be helpful is the ability to manually tag vertices as locked so they don't move while relaxing. For example, if I'm retopo'ing scanned clothing, and I don't want vertices along a natural stitch seam to move while relaxing, I would select that edge loop and lock it.
