Settings are easy to find and understand. Tag creation and modification is easy and straightforward. Online documentation, while complete for defining features, could be a little better. It would be nice if there were whole example pages. Sample text or more thorough explanations for common tags would also be well received.
Installation is a breeze.
Simply unzip the program files to a temp directory, and run install. Document loading is also very close to System Editor's times. Some power features I would like to see in future releases are CGI support and MAP support for graphics. I would even be happy if these were add-in modules that cost extra. The ability to crank out multiple pages easily and uniformly is very worthwhile.
