One thing that always borthered me with newer version of Safari is the new mute icon.
Before mute icon had a line that crossed it. making it easily readable that the tab is muted. where in newer versions it just removes the sounds waves. making it more unclear if its just turned down or actually off. obviously you understand after a while that no sound waves means off. but its still harder visually to see the difference then it was before
