In the current version "FFF Settings, Cooling" tab there is only support for one cooling fan. On printers with separate x-axis extruders (i.e. MakerGear M3 Independent dual extruder) or other configurations with an extra cooling fan, it would be desirable to be able to control both fans independently.
I believe the current cooling tab can be enhanced to provide support for two or more fans without cluttering up the existing UI. Perhaps and "Advanced" button to switch to the multi-fan version.
