The 40s/ortho kit is missing a few keys/requires a few changes. As it stands right now, your 40s/ortho kit offers ortho-only support, even though you offer several non 1u sizes.
-1.75u shift is strictly a left sided key in 40s and should be blue, not sand.
-1.25u tab in blue in missing. Every single staggered 40s board uses this key size tab. This is a quintessential 40s key.
-in order to outfit a prime_e, you’ll need another 1.25u key in blue. I recommend Fn or Menu
-in order to outfit UT47/Whimsy, you’ll need a 1.5u shift in blue
-I recommend 4x total 1.5u bottom modifiers. This covers some iterations of Fourier/similar layouts. Such as 2x blue and 2x sand (Ctrl and Alt)
-other common small bar sizes are completely missing. You’ll want to add the following: 1x 2.75u, 1x 2.25u, 2x 1.75u, and 2x 1.5u.
I’d be happy to go over these changes with you in greater detail on Discord. DrHigsby#8817.
