Good work on the new release. As a long time Scrivener 2 user, I'm happy to see this.
However, I wanted a simpler and subjectively nicer looking tool for distraction-free writing and thus made my own. It's free, has a few social features built-in, tracks writing progress/goals/distractions, and can make good looking books.
Also, adding features to Singular Writer has been really easy, as evidenced by it being in existence for a few months. For the Windows crowd, we've had feature parity from day one.
Check it out if you want to write more [with friends].
