I second most of what has been said
-ISO enter novelty could be enhanced with something like a bent pizza slice, like a Dalí melting shape, to follow the layout of the key
-“salty” must go
-ISO Italian, well it would be nice but after seeing pbt Amalfi missing it, I lost my faith anyway
I would add
-novelties in 1.5u for WKL users?
-I would switch the design of novelties on ANSI enter and backspace. Reading from top to bottom, if you use both, it is now “Pizza peppperoni” while switching it would make more sense maybe. And I would use the same color scheme of the enter for both, to blend them in the set (maybe it’s just me, I like when novelties are subtle, like Easter eggs that you don’t notice immediately)
-the brown to recall the crust is very nice but I’m wondering if it would look nice on a 65%. It would be all brown just on 4 keys on the right if I’m not mistaken. Sounds weird.
-just throwing an idea on the table: a touch of green to recall the basil? I know, this is inspired by a pepperoni pizza, not by a proper margherita, but still...
