I know GMK Merlin's 40's kit didn't do well - considering the ratio to base kits sold I'd say it did better than some sets actually - but we'll you please, please, please consider at the very least adding min. ortho support to the base kit or the spacebar kit? Yellow is one of my favorite colors. You'd only need 4, 1u keys:
r2: Out
r3: Data or Read
r4: Shift and Enter
Thanks for considering Merlin!
