Some more feature requests...

 - Perhaps trivial, display Temps in both C and F on the admin interface.

 - Re: ability to swap pools around easily... perhaps just a UI change to the config form... add ability to add pool rows, but also include a tickbox to enable/disable them, would at least save the copy/paste shuffle step.

 - I have some IO/GPIO ideas too, but I need to take a closer look at the beagle-board black that bitmain is using.   (Like the ability to add an ambient [intake] breakout temp sensor, and trigger shutdowns or profile changes that way too).

Fan 0 Setting...

Is my understanding correct that at this setting the firmware cares zero f*cks about what the sense cable says.  You mentioned this enables 3rd party fan mods... so is it still gonna spew 12v on two wires, but do nothing with the control and sense?  Or are you implying powering the 3rd party fans directly off the supply?

Cheers!
