 * add option to ignore z bottom in CAM contouring
 * add CAM pocket option to ignore interior features (outline only)
 * add CAM Z bottom visualization, make it relative to stock instead of part
+* add CAM z bottom inversion option to flip operator
 * extend url loading of workspaces to all formats
 * alert when healing is enabled and non-manifold geometries are detected
 * fix thin output start and end point tracking which broke retraction
