Maybe I'm missing some funky new ortho layouts or maybe they're for a language I've not come across but the R1 and R4 #~ keys in the ISO kit seem strange and the R1 \| is more HHKB than ISO.
It's a good looking set anyway 
ISO is now fixed!
Changed it is, but fixed? I guess it is as it will now cover UK and US ISO layouts but you still have the strange R4 #~ If it is needed for something please say what so I can learn 
Also the R1 \| may not be ISO but lots of people use the HHKB layout and will want it somewhere. They can't cover the board using just Alphas plus Ortho or Mods even if it was added so I guess it could go in either. This balancing act is why the perfectionist in me could never run a GB - compromises must be made and some unlucky people will have to buy a big kit to use just a couple of caps or everyone has to buy a huge all-in-one and not use half of them. Not sure which is worse...

Ah, the extra #~ is a fairly niche thing. I tend to leave it for those who swap pipe and that key, since I know of a few who prefer it that way. Otherwise, for sure on the balancing act. SA tends to have high MOQs for kits, so it's tough to make a proper compromise, especially when it comes to ortho/40 boards. As a 40 user and maker myself, I want to expand the compatibility as much as possible, but I have to draw the line somewhere, lool
KAT sometime, just maybe...
