I agree that the Settings page is a pain to use or find anything. I prefer everything to be displayed in one page so I can do a quick Cnt+F and search for the string I am looking for instead of tediously mousing over every button to expand. See Jenkins->Manage Jenkins->Configure System

Oddly enough, I stumbled on the fact that Ctrl-F works fine on these pages. All of the items below the expands are still visible to the search, and the expand automatically pops open when your cursor jumps to the matching text.
