With light switches and a compact layout it's not too bad for navigation. My default for arrows is LeftThumb+HJKL, so it's quicker and more natural then diving for the arrow keys. I also have overloaded alphas (Ctrl on a or ;, Shift on Z/?, etc) so Ctrl-Shift-Up maps to A+Z+LeftThumb+K. Seems a little bonkers but it only took a few days to adjust to my GergoPlex [0][1]

The bigger issue with adding more keys to the mix is that with heavier switches (35g+) the amount of work/stress done by the hand can be more then a traditional keyboard. But even with heavier switches it's often faster then having to move your hands around the physical board. And once you factor in things like combos you can just map End to something like QW or whatever works for you. Programmable input devices are _really_ weird!
