Some weeks ago, I tested Evince, the GNOME’s pdf viewer and I found the way it displays the results of a research (crtl + F) very useful: all the results are displayed in a window on the left of the document, with their context of occurrence. I helps a lot finding the result we’re interested in. I hope one day that feature will be implemented in Okular, as I prefer using it for its other features 🙂
