PandaWare has a new version of their Simple Help Editor available in pre-release format, and they're interested in getting feedback from experienced help authors. The new version includes changes to make it easier to re-use content across different versions and the ability to prepare output for compilation into a CHM file.
To get the free test version, sign up and specify if you'd like to test the Windows or Macintosh version, or both.
