> i think the spacebar doesn't need to be so big, there's no reason for it to be available to both thumbs
This is why I love JIS, even though I don't actually need the Japanese keys. That small spacebar is so much better, and you get three extra keys (Henkan, Muhenkan and Kana) along the bottom row. As an Emacs user, I bind Henkan and Muhenkan to be Control keys. It's very comfortable.
I was just thinking this today tweaking the layout on my lilypad58, a layout I don't love and kept arriving at, "I just want more modifiers". Using JIS is genius.
I have left Control mapped to Meta, {,Mu}Henkan mapped to Control, Kana to right Alt, right Alt to Super, Menu to Compose/Meta (tap/hold) and right Control mapped to Greek.
I use keymapper[0] to do low-level remapping and tap/hold, and a custom XKB layout for the Greek modifier. I highly recommend this setup.
