Headus updates its UV layout tool to v 2.06. A new feature includes Repaint which allows you to load an old mesh and texture map into UVLayout where you can then modify the UVs (e.g. repack, optimize, modify seams) and repaint the old map according to the new UVs. The update also includes some new functionality to existing tools, for a complete list of new features, check the headus forum on UV Layout.
UV Layout runs on mac, windows and linux, even tho the mac version runs under the x11 environment, with an interface that looks like it is from 1993, UV Layout is an absolutely amazing and simple tool for unwrapping UVs on meshes.
