@leocg Thanks for answer)

I just recently switched to Opera gx, and am not yet completely familiar with all the functions of the browser. Does this browser have a feature to switch backgrounds on the browser desktop? For example, I set my background in a futuristic style, but to be honest, it only looks beautiful in the evening; in the morning I would like to put a different background.
It would be inconvenient to manually change the background every time, is it possible to do this somehow automatically?
