Looks nice - I enjoy Dolch.
Agreed on the suggestions prior by Gtour, and some other items below:
- all Print legends --> Prt Sc (including in the R0 kits)
- I think the positioning for the legend on the BAE looks awkward. I think it will look better if it can be like an ANSI Enter (but with the 1.5u sized forehead), like it was done in GMK Beige Addon & Extension's BAE kit.
- The R0 kits are missing keys to make it compatible with 1800-layout (and similar) boards. So that'd necessitate R0 Del, End, Pg Dn in the base kit, and all R0 child kits.
