Sorry noob question - whats missing for Full ISO support - the base image looks to have all the keys I would need for 60% where are the gaps?
The least amount of different keys to make a proper ISO support board would be UK I think.
I think it's 6 keys + short left shift + vertical enter. Those 6 are
R1 - [`¬] [2 "] [3 £]
R3 - [' @] [# ~]
R4 - [\ |]
When you get into all the different variants of ISO it expands a lot more though.
End of the day, I'm not sure for how many ISO users I speak for, but having physical ISO support is meaningless if the legend support isn't available to have the correct key caps. Might as well just drop physical ISO to save money for the rest of the ANSI only userbase. Even more so when the price for keycap sets are what they are. It's not worth it getting a product not fit for purpose when one of the main points about the mech hobby is preference, which to some is the ISO layout.
