Thank you for adding a Colevrak kit! This kit could be called Colevrak+ or Typist since it covers more that just Colemak and Dvorak: DH & DHm variations of Colemak; Workman, Norman, Carpalx QGMLWY, and QWPR. Perhaps more.
Adding an R3 non-homing U would give every supported layout the option to run without homing keys. Adding an R4 ' " keycap would help anyone using Programmer's Dvorak.
And please don't take this the wrong way, but there are two typos in the kit render.
Regarding the Numpad kit, is 5 a homing key?
