@leocg Thanks for the help!

Hello! I am having a problem with the sidebar in Opera GX browser. The problem is that I would like the sidebar to appear only when the mouse cursor is over it, and not constantly. Bored quickly. And if you remove the sidebar completely, then I miss some functions ... Can I somehow make the sidebar appear only when you hover over it with the mouse cursor? I would be very grateful if you answer my question! Bye!
