The aim is to produce the most fluid one handed typing possible without distracting stretches between keys, as the rolled combination can generate any combination of letters.
Indeed. The sheer amount of state that chords can occupy is proof of quite how inefficient standard keyboards are in converting movement into output.
That balance of learnability versus fluidity, two vital things, will be quite the challenge!

Exactly. I had all manner of layer remaps
and macros in mind for my (then still to be built) custom keyboard. But actually using the working hardware led me to immediately alter almost everything! Some things have to be chosen by your fingers, not your head.
As for my build: some of the surface mount resistors are required to make this work, besides those for the LEDs? Perhaps I'll join you on the 7bit waiting game for PCB mount reds while I source them. My tall caps have a good feel, but will need some well glued plate mount switches, and I'm wary of committing to one switch type before I've tested it.
The caps are Signature Plastics SA profile
sphericals (which I've a strong fondness for these days) like 7bit's current Round 5
. I put row 1 on the top, 2, 3 and 4 in sequence for the single unit caps. Seems to work quite nicely. They're likely all available individually from SP as blanks. My legends are clearly superfluous!
I assume A = anode and K = kathode (in Cherry-speak) for the LEDs, as your legends match up nicely with the diode markings on the switch bodies themselves. (Technically, those markings are for the optional diodes, not LEDs, that Cherry can pop inside for you. But I assume the polarity is the same.)
