Thanks for testing out my build. Regarding the camera, I also provided MIUI camera, which should behave a little better... regarding the battery life, I have intentions of producing my own battery savings kernels, just like a did for the Atrix, it will take a little time to complete... I have to say that I came from stock build and the battery life is much better now... it even compares to Unity...
Not to take anything away from this build. It's a great build. I'm just spoiled by the sense camera snappiness and battery life (ironic that it's so good now). You've done a great job with cm7. Can't wait for the new kernel!
