I was initially hopeful there’d be something to play with by the end of the year, but that’s basically out of the question now. Between the fixing the issues with iOS devices, getting my billing compliant with VAT/taxes, and other no-fun-but-absolutely-necessary tasks, I am already going to be scrambling to get everything done before we go out of town for Christmas.
New strumming patterns remain my #1 goal and the thing I want to work on the most. But I don’t always get to work on what I want to work on. 
Hopefully in January I can focus more-or-less exclusively on this and have something out in the first few months of 2022. [Update: Most of January got taken up by stupid-but-necessary tasks related to taxes and legal requirements… but as of the last week of January I’m finally able to focus on building these new patterns.]
