We have a small handful of functions that reside in the top toolbar for the Retopo tab
If the mesh has multiple UVs, you can switch them in that drop-down list.
Move Select: Move selected faces to another UV set.
AutoSnap: Snap newly created points to the surface automatically.
- Snap to Closest Along Normal: Snap to the closest point on the surface along the normal of the retopo mesh.
- Snap to Outer Face: Snap to the outermost surface within the designated threshold.
- Snap to Nearest: Snap to the nearest point on the surface.
Additional Extrusion: The additional extrusion of the mesh. This value will be used when you transfer the mesh into the scene. It could be useful for making cloth.
Z-bias: This z-bias value will be used to improve the visual appearance of the mesh. Adjust the z-bias to get a better look at the retopologized mesh preview.
Retopology mesh opacity: The current group gets this opacity; other groups are getting 50% of this opacity, and other UV sets are getting 25%.
Colors: Edit Retopology Mesh and UV island Color.
When you select an Retopology/UV islands colors, each color cell corresponds to a polygroup.
Radius: Change the Brush Radius.
Invert Mirror: Enable this option if you want to invert the direction of symmetry mirroring.
Mirror Snapping: This value determines the degree of snapping of points close to the mirror.
Various view modes for the retopo mesh: With no checker, with a simple checker, with a complex checker, and Custom Texture.
Separate options for wireframe, seams, sharp edges, colored islands preview, and smooth mesh view.
It is very useful as it shows the distortions of the texture in different areas of the mesh.
New 2D Primitives
Added new tool for creating 2D primitives for Modeling and Retopo rooms:

Unify Multiple UV Sets into One: If you have a scene in 3Dcoat with multiple uvmaps (UVsets), you can consolidate them into one.
