When I create textures I sometimes don’t have any/enough padding around the UV islands which might end in nasty seams on the 3D model. This tool is able to extrude the island borders by a given value in order to overcome this issue.

All the bakers out there offer this functionality but in situations where you don’t want to or can’t rebake this software might come in handy.
(You will want to take a look at the Readme.txt first though. )

Currently there’s only a Windows version available but the code is platform independent so  let me know if there’s demand for Linux/Mac versions.
