Currently, Web Inspector displays redirect HTTP request as a sub-entry of the final request. This is a different behaviour to Chromium and Firefox. It often causes me minutes of incomprehension whenever I'm debugging those kind of HTTP behaviours in Safari, until I remember where to look.

Even though it was a neat idea, I don't think it helps me debug faster. And with Shift Key to highlight initiated requests, it's easier to establish the relation between two requests.
