You ask a lot of something I'm giving away for free 
But to be honest, those are both things I'm considering adding. I've planned to add EWBF and Claymore, giving the user the selection from 3 diff miners (genoil ethminer, claymore, ewbf). As for showing the hashrate per card, with ethminer that would require running one instance per gpu, which works fine, but looses maybe 2-4% efficiency compared to running one instance on all GPU's. (Ive been testing this for a farm sw model Ive been contemplating). Oh and just saw your last question - Im updating it to 16 (the most the nvidia driver will index) for the next revision that'll likely be out in a couple days.
