I said a few of these things in my IC form so apologies for the repetition but there are few things that I think should be noted here too.
I'll state by biases upfront and say that I really can't stand it when number pad caps have navigation legends on them as well, but I think that for such a minimal set it really clashes, just the way that it does on sets like WoB (but yes, I know, preferences). As you put the decision on whether they should be included or not up to vote in your Discord, I think that you should have the same option here on Geekhack too. In Discord, there's only been 30 or so of us who have responded which is a really tiny sample size, especially considering how many reads you've had here on Geekhack. You could open up a new form, as those of us who have already completed the IC form won't be able to go back and edit.
Thank you so much for including a UK ISO kit, but the renders for the kit are wrong - the 2 and 3 caps are those used in Portuguese ISO (I think) rather than UK ISO. The board renders with ISO are UK correct, though.
Lastly, it's a shame that the r3 function and numpad = keys have gone from the extension kit. The former, I'm guessing really doesn't have a huge amount of demand (and you've chosen a r3 stepped super in its place) but the = key is more and more becoming part of base kits. I'd suggest having it there, but if not it'd be a real shame not to have it in the extensions. Speaking of the extension kit, how possible would it be to have a barred 5 cap as you're including the barred F and Js? Last but not least on this kit, I don't think that the 1u AltGr cap makes much sense and should be simply be 1u Alt to go with the 1.5u supers. As they tend to be used with MacOS/Linux, the graph designation is redundant, no?
Regardless, GLWIC; this is an exciting one.
