I am making some progress towards creating a replacement (yet to be named) for RatioKey. Of course, that is no guarantee it will ever be published, but I'm feeling more hopeful in that regard.
I'll post any real milestones here, but if you would like to follow this project in more detail, I've created a Twitter account just for that: @harmonicLattice. That handle contains a hint about what I'm currently working on, but only a hint.
