Hey Zambumon,
I'm really liking the kit updates for Jamon and love that you are wrestling your vision for products and pricing into reality. Assuming from the Jamon update that you're taking all accents out of the core and into a separate kit to keep the core cost as low as possible:
I'd love to see a combined accent/novelty pack that's as afforable as possible. Judging by the $35 quoted on the Massdrop Nautilus Nightmares voting page, I imagine this will be quite difficult.
(As an aside and and slightly related - Without knowing cost yet, it may too expensive for me to pick up both Jamonelties and Pata Negra).
Here's what I would hope see in the kit:
Esc, Enter, and Arrow key accents (don't see the arrow cluster in the kits or renders - are they being left out? Also, keep the numpad accents in the numpad kit).
A mixture of Novelties. Ideally I'd like some 1.50 Code or Fn keys if they're not going to be in the core, but if this significantly increases the cost maybe it's better I make do with the non-specific icon novelties you've already shown.
In my case, I use a funny layout these days for my bottom row (alt, fn, fn, os). Novelties or just having key legends that don't match my particular usage scenario is probably preferable to an increase in price that would turn me away.
One last thought: Do you have interest in using Alt Gr legend?
