It would be nice if the Inspector had some sort of "mini-view" that was always visible that would show you some succinct, essential info and give you quick access to the Inspector. This could take the form of a bar at the bottom of the WebView. Perhaps it would have an error/warning count and resource count. It may not even need anything more than that. Clicking it would show the Inspector.

(Just Some Guy) That sounds awesome! This would be really valuable =). Hitting ⌥⌘C is currently a little hairy because it brings up the entire Inspector and often blocks a majority of the page content.
