I just switched from Google to Opera GX, and I notice something that a minor inconvenience is that there is no option to have something like Google's browser tab media control. I can't have multiple tabs open at the same time and control them all. The player is also on the sidebar, which I turned off and on most of the time for viewability. I wish they would add an option to add something like that to Opera GX, or at least have the player be on the top toolbar instead of being on the sidebar.
