I have a few potential improvements for the kits that I'd like to suggest:
- The second R4 1u Fn key is redundant and should be removed.
- R1 1u Backspace is a seldom used key and can be safely removed, especially since there's a R1 1u Delete that can be used in its place.
- R4 2u Shift is also a key that's rarely used and can be removed, although one benefit of keeping it is that you get a mod colored 2u space replacement without buying the spacebars kit.
- The R2 1u + and R3 1u = numpad setup is very odd and, I believe, very rare. I suggest replacing those two keys with a R1 1u =, as equals is commonly found next to Num Lock / Clear on standalone numpads and Mac keyboards.
- The ISO support, as it stands, is partial and inconsistent. Either add the few R1 keys that are missing for ISO-UK support, or replace the current R3 '@, #~ and R4 \| keys with R3 \| and R4 <>.
You should add a centered stem, alpha colored 6u spacebar to the spacebars kit.
1) Was purposeful, keeping it most likely (might change)
2) In the kit because I want it, true split backspace support (not-hhkb moved backspace "split backspace").
3) It is seldom used but most likely keeping it in. May change down the road, who knows.
4) I put this in because it is my preferred numpad layout but very rarely supported sadly.
5) Probably keeping it as is, I know it may not be full UK-ISO legend support but it is what it is.
6) I originally copied my Night Runner kits and didn't have 6u in them because I really didn't think it would be needed, but after having a topre board and running into that issue myself with a set, I will most likely add this in.
