- Stepped capslock appears to be missing.
- CONTROL can be written out on 1.5u and larger keys
- BACKSPACE instead of DELETE for the 1.5u key seems more appropriate
- In numpad, color of extra 5 and 1u + key should be the other way around. Also R2 minus and R3 plus instead of R2 plus, as splitting the 2u + into + and - is the norm
- What's the extra modifier color 1u Del key in the TKL kit for?
- I suggest using the bigger function row legends SP has available.
- The Carbon-style color mix of the TKL mods seems a bit odd when not using an accent color
