Easy to use Ghostscript IDE.
Allows you to easily edit and view PostScript (multi-page PostScript) files, convert your files between different formats (PDF, PostScript, TIFF, PNG, JPEG, other...), view PDF files.

I think the screen shots show promise, but it crashes on run 100% of the time. Perhaps needs better documentation.
