I won a split #MechanicalKeyboard, a #Lily58 Pro. I'm only using a 5×3 subset of each 6×4 half to see if I can. Adapted from the #Miryoku layout: hold down a thumb (and needed home-row mod keys) on one side, type a key on the other. Green Symbols, red Numbers (and Pairs), blue Cursors, yellow Function (plus Media¹ and more symbols), with a White base.
Colored diamonds on Menu key are layer locks². Dash of Green: Column TGB is EmDash, FigureDash, EnDash. Volume key is actually a knob. Green thumb numbers are superscripts.³ I've tried to make key placement logical to help memory. Lots of unassigned slots (rounded corners).
I have a vertical version of the layout as wallpaper on my portrait-mode monitor, and have defined Super+A as a second hotkey to Show Desktop: Pinkie+Pinkie. You would not believe the hours I've stared at it thinking of new ideas or better arrangements.
I hope to actually get the #layout on the #keyboard one day, if I learn the intricacies of the #Configurator and if #QMK flashing works for me. At the moment the former is a minor problem, the latter a bigger one.

[1] Prev|Next icons should be single triangles pointing to a line, but all #KeyboardLayoutEditor offers is doubles arrows doing so, so I'm experimenting with alternatives.
[2] Red Numbers may be the only layer it would make sense to lock, but I put them all in. No NumLock, and CapsLock has been seconded to Compose (⚘), with its toggle function set to Shift+Shift in #LinuxMint.
[3] I clearly use them, and symbols like bullet and starburst. When I used Windows, I had many simple character macros in #TSE (The Semware Editor) to enter them, like Alt+Shift+Period to produce a bullet. Kate doesn't do such, so I had to resort to learning Compose sequences (• is Compose . =). I can now fix that at the #keyboard #layout level.
