I'd strongly advise you look at the kitting of other upcoming keysets in IC right now and see what more you need to add to this.
Second to that it'd also be pertinent to mention how you plan to bring this to reality (vendors or self-managed), what vendor you're using, materials and manufacturing methods?
I'll look at the other keysets to see what else I could add. I know for sure I'm missing a few keys like the 1u ctrl, alt, hypr keys.
I'll also update the post in just a second but generally, the plan was to be self-managed at
https://hackrlabs.dev/ (it's down since it's still a WIP) but I'm open to doing it with the help of vendors if it's easier that way! I'm not exactly sure what the pros and cons are or if I'm able to do a mixture of self-managed + help from vendors.
And finally, manufacturing so far is pointing in the direction of doing with dye-sublimated pbt keys. I got an initial batch in but some colour tweaking needs to happen so I will accordingly update the post once I have those in!
