Had my N7 for a few days now and I love it. First thing I did, right out of the box, was root it. After doing some research I installed Franco's Kernel. I'm happy with it thus far, so I bought the updater app on play (keep on cooking Franco). Suddenly I have a whole bunch of options an not much of an idea of what they do. I more or less understand the governors. But the other options, like undervolting, I/O scheduler, etc escape me. Anyone willing to teach me a bit?
