It works on Windows, Linux and Mac. On Mac it doesn't detect your CPU model and just calls it "CPU" - I'll fix this in a later release, but it's a little difficult without a Mac to test on.

The tweak thing is for all the settings for each GPU, instead of all the -a -b -c -w options other miners have. For now it doesn't remember the settings when you restart the program - this will also be fixed in a later release.

Feedback welcome! How fast is it compared to your regular miner? Is your GPU detected properly and the red/green markings on the gauge in a sensible place? Any bugs?
