Okay, so the average hashrate line became a lot of commits. In the end I just made it simply a horizontal line as it looked less cluttered with dots and I think this makes it more clear. Can explore the backend average hashrate, but I think this is a good solution in the mean time

LGTM only nit comment is that not sure if I prefer Mhz being moved. I assume that was for setups where we run it at 1Ghz or higher?

Yeah, once you go over 999mhz it hits the knob around it

If you want instead, we can format the number to Ghz then. It just looked crowded to me, but over 999 is the real problem
