MTNU vendors tend to favor monokits with the numpad included (and often no other child kits). The base kits for MoDo and Skyriter (the revised version) are good examples I've heard multiple vendors say to emulate.
Since GMK has a standardized NordeUK kit with UK ISO included in it (assuming UK and EU vendors are willing to buy it out and get it made), the base kit usually just has terminal ISO in it.
Because of R4's bottom lip, including a R2 up arrow is popular - it's easier for fingers to slide between the up and down arrows with that R4 bottom lip removed, and makes arrow homing easier on non-exploded 65/75 boards.
You'll probably need to make the 40s keys mod-colored rather than accent-colored - forced accents generally draw complaints from people who don't want to have to use the accent colors.
GMK—I understand the mono kit, which, in my opinion, makes it less desirable than me. I suspect 70 percent of the keyboard hobby does not have a board with a number pad. I'd rather save the end use the difference in cost or use the plastic to increase compatibility—IE full UK ISO, Alice, etc. instead of a number pad.
On the accents, I am getting conflicting feedback on the minivan mods vs. accent. I'll let it shake out. I think the grey mods are a bit too dull so that I will keep them for now. However, if more people want them, I'll be happy to modify the kit if people will use it.
I've had people on the IC ask if I had a Discord. I did not,
, so I made one. I will be relatively responsive there as things progress.
The next thing for Welles: I will have an accent kit before the long weekend ends. The "first draft" of it is at the bottom. I have concepts of what I want to do for the novelties, but I am working through either A) DIY or B) finding an artist to collaborate with. If you are in column B, reach out.
