Nice looking colorway! Love to see it in Gorton and DCS.
Have a few suggestions/comments for the kitting if you'd consider:
1. Would you consider doing classic styling for legends on the navigation cluster? i.e. "Prt Sc" / "Scroll Lock" / "Pause"
and "Delete" instead of "Del" for both R1 and R2 keys. I'd also make sure Pg Up and Pg Dn are spelled with a space between "Pg" and "Up/Dn"
2. Could you consider doing the thinner / corrected versions of tilde and quote/apostrophe? i.e. `/~ and ' "
This applies to both base and alt alphas kits
3. Can R2 1.5u Backspace be "Backspace" (one-line legend) instead of "Back | Space" (two lines)?
4. I see that a Tab, R1 2u Backspace and R2 1.5u Backspace were added to the Alphas kit to enable putting the set on two keyboards. It seems the color on these two Backspace keys should be the lighter blue. The R2 Backspace is also inconsistent in legend choice with the Base kit's.
5. Can there be a 6u spacebar added to Alphas kit?
6. I would suggest adding R1 Pg Dn and R1 End to Numpad kit to enable 1800s support.
I think that's all I can spot for now but please do consider these changes!
