ixtab, you've figured it out already, the screenies are from KUAL 0.5 pre-release, with your 0.4.1 changed merged in manually. I haven't had time to push the code yet, I'm going to RSN.
ixtab, the new buttons look GREAT on the lower devices. No more fat bubblegums on the K3/K4/DX. I think people will appreciate that - the way it looks matters!
