I’ve been trialing Chaptarr (not affiliated officially with the ARR stack). Still new, so can report back with initial thoughts

I use a ZSA Moonlander which I programmed to have 2 Ys and 2 Vs so the left and right work like how you’re looking for.

It sped up my adoption of using a columnar keyboard. I’m sure some will say I gotta fix my typing, but I definitely have sped up my typing with a split keyboard, even with this quirk.
