I was just told about this software. It mimics most of what I love about QMK: homerow modifiers, layers, remapping keys, and more, but it does so at the OS level. This lets it work on any keyboard, such as a laptop. I'm guessing the configuration is accessible, as it's a LISP-style file you load from the command line. I'm going to try this.
