Love love love this. I'm a huge coffee fan it's probably my favorite part of the day. I have a few points of feedback.
I'd much prefer if this set used icon+text mods (like og cherry). I think it'd fit great with the soft spoken and subdued themes of the key set.
Also, is there any chance you could add a 1.25u r3 tab key? This expands the base kit to fit a majority of 40% keyboards (at least with respect to size/profile). I'd be happy if this legend was enter, tab, ctrl, or really anything honestly.
Potential keys to remove to accommodate this: r1 pg dn, r1 end, mod colored ` key, or r4 1u ctrl/tab (forcing people with tada/60 with arrows to use novelties instead).
