Turn the calibrated card on and off with a single press.
It is necessary to have a built-in function for the top and right panels, which in one click turns on and off the layer of visible calibrated maps (or sets the transparency to 100% and then returns to what was set). When using a calibrated map, it is often necessary to briefly review the real map and see the calibrated map again.
Two press it's been a very long time. :-)
