Ergonomic, split and other weird keyboards

Rules

Keep it ergo

Posts must be of/about keyboards that have a clear delineation between the left and right halves of the keyboard, column stagger, or both. This includes one-handed (one half doesn't exist, what clearer delineation is that!?)

i.e. no regular non-split¹ row-stagger and no non-split¹ ortholinear²

¹ split meaning a separation of the halves, whether fixed in place or entirely separate, both are fine.
² ortholinear meaning keys layed out in a grid

Introducing Kühlmak, my layout analyzer and optimizer (github.com)

After a few years of tinkering and learning I'm finally ready to share the result of my work. Meet Kühlmak. What started out as my attempt to create the perfect keyboard layout morphed into a project to make a flexible and fast analyzer and optimizer. The feature highlights:

Command line interface
Information-rich, text-based layout overview and stats
Support for different types of physical keyboard layouts and fingerings (row-staggered, angle-mod, column-staggered and more)
Extremely fast analyzer that enables simulated annealing
Multi-threaded annealing to find many optimized layouts quickly
Multi-objective fitness function with soft targets for individual objectives
Multi-objective ranking system to identify the best trade-offs out of many generated layouts
Metrics that naturally favour finger and/or hand balance for effort, travel and n-grams
Finger travel distance weighted by speed (inspired by Semimak)
Comprehensive same-hand bigram, disjointed-bigram and same-hand 3-gram scoring system
Support for affinity of Space to one thumb or both
Optional constraints to enable steering certain layout features (e.g. preferred positions of punctuations and shortcuts)

The terminology and metrics are partially inspired by and partially adapted to The Keyboard Layouts Doc (2nd edition). However, I made some deliberate design choices and probably introduced more subtle biases that deviate from some of those definitions. There is lots more information in the README.

At this point I consider it ready enough to finally optimize a layout for my Mantis keyboard and see if it works as well as I hope it will.
