Address Bar Highlighting

I am the kind of person who likes to be able to know something from a quick glance. In this way, I think there should be an option to show more intense highlighting in the address bar. I use URLs all the time, and I would like to be able to read them easier

Example concept (not very good):

encoded characters would have a friendly preview, but expand when the address bar is focused

of course, these colors would be different with different themes
