 ** TODO
 
 - fully implement a sane extended layer like [[https://dreymar.colemak.org/layers-extend.html][this]]
 - maybe completely remove the NAV and TAB keys
+- maybe figure out home-row-mods: https://precondition.github.io/home-row-mods#how-to-use-home-row-mods
+  - inspiration: https://alexschroeder.ch/wiki/Atreus
+- build a real split keyboard (5x3 + 2x3 thumb)
+  - e.g. with PCBs from here: https://keycapsss.com/keyboard-parts/pcbs/53/crkbd-split-keyboard-pcb-corne-helidox?number=KC10022_CHOC_BK&c=6
