> Get rid of the num row and limit movement for fingers to one key in any direction using layers to simulate the missing keys (corne or kyria)

Wow this is first time I hear this recommended in relation to keyboard ergonomics. As a user of compact 49 key keyboard without a num row, can at least confirm it is not bad for productivity. Numbers and symbols are on layers and thus spread over keyboard. As a programmer I use a lot of symbols and I like the compact layout more. Precisely because there is less weird finger movement away from working zone.

Another thing I can recommend on regular keyboards is angled home row finger position: sdfv and njkl instead of usual asdf jkl;. With corresponding change to zone of every finger. Elbows on arm rests, wrists are straight.
