In trying to find elements with the same classes we could click on the target icon below the selector field. (The one that indicates how many elements has the same class) In doing this, the box of every element with the same class turns pink.

But a nice step-up would be to make the navigator's elements also get highlighted which is actually more easier to see than trying to find elements that have pink borders. This also helps with finding for hidden elements or if the website's design makes it harder for us to see the pink border frame.
