It is high on our priority list to address this issue of the plugin apparently not showing up on some systems. Presumably you have copied / installed the dll to the folder that the program expects, and have scanned for plugins etc. Some programs have a blacklist of plugins, and perhaps it has been added to that list.
I will mention, on many systems including the ones we tested, it does just show up and work.
Yes - we are planning to have dedicated documentation/videos for each program.
