how can I hide jar files in the project explorer? In previous versions of eclipse it was possible to hide them with "libraries in project" filter, but I don't find that anymore in kepler. Now there is only "libraries from external", but that's not enough, I still see a lot of libraries in my project on the top level.
Context: I've imported a play 2.1.3 generated project into eclipse kelper, and I have a lot of jars in the lib folder.
