Update on the 2.0.0 release & the full manual

We are getting close to the 2.0.0 stable release and the full manual. The manual will soon become available on the website and also in PDF format. Both versions will be identical and once released, will start to follow the APP release cycle and thus will stay up-to-date to the latest APP version.

Once 2.0.0 is released, the price for APP will increase. Owner's license holders will not need to pay an upgrade fee to use 2.0.0, neither do Renter's license holders.

I love the new star reduction tool.  Below is a quick video that shows my initial thoughts and experience using the tool.  I would love to see a discussion get started about how to use this tool better.  What can I do to make it work even better?

Thank you Joe for posting this excellent tutorial!  I downloaded APP 1.083 Beta2 to try the star reduction tool but I was lost until I found your video

Here is my first attempt at using the tool after watching your tutorial....

Hi Joe,

Very nice tutorial on star reduction.  I wonder how much more effective the user community would find this useful tool if the instructions available by mouse hovering were a bit more detailed.  Or maybe a link to an instruction page that showed the effects of individual sliders (showing blow-ups obtained at 10% and 90% slider positions) would encourage more users to try star reduction.  I found your quick tutorial provided details that increased my understanding -- so I'm not asking for much.

David
