Option to hide blue/red cooling/heating background coloring on the graph

[vanosg]

In a long fermentation, it gets hard to see the temperature/gravity lines in a highly-cycling fermentation. Similar to how we can hide temperature, profile temperature, gravity, etc- can we hide the blue/red background that denotes when a cooling and heating cycle is taking place?

I would also appreciate the implementation of this option.
