Good morning.
First, I wanted to congratulate you on your two good products, Scrivener and Scapple. Although my view I think they are very improved, no doubt they are two great products.
Regarding Scapple, I wonder why the latest version is 2013 (version 1.0) and, most importantly, if there will be a version 2.0 and when it envisages, if necessary.
Thank you for your attention.
Scapple was written to be a simple and useful utility for everyone, us included. 
We do have lots of ideas for improvements that we would like to add some day, and we will do so, but right now our priorities are on Scrivener, since Scapple already does 100% of what we wanted it to accomplish—and on Windows especially, we have much to do to finish fleshing out Scrivener instead.
