Question

I need to work with Eclipse source. And I have many packages imported:

org.eclipse.core
org.eclipse.jdt
org.eclipse.jdt.core
org.eclipse.core.resources
etc

So I have all this packages in my project. How can I divide them by their tree? So they look like this in my project:

org
  +
  |- eclipse + 
             |- core
             |     +
             |     |- runtime
             |     |- resources
             |- jdt
                  +
                  |- core
                        +
                        |- dom

Srinivas Thatiparthy’s comment was close. There is an option "Package presentation" under another button that is next to the button similar to "-><-".
