Nice! I wrote about something similar for rectangular layouts: https://maxhalford.github.io/blog/dynamic-on-screen-keyboard...

thats wonderful. id like that to not change the order of the letters - but change the highlight order. Do a round 1 of frequency order first (just do first say 6 letters) then do a round 2 which is standard order..

i probably am not making much sense. Look at where I'm coming from in the world of Assistive Tech - https://docs.acecentre.org.uk/products/echo (go to around 5 min mark in the vide)

How about a backlit keyboard, and if the next letter is probably a vowel, only the vowels are lit?

I'd be quite interested in trying that. Maybe as a learning aid. But if you get your typing speed up, I can see it being visually very noisy.
