The list of jars just takes up too much space. Can I collapse it or hide it?
In Eclipse3.5
In Eclipse3.5, select the filter "libraries from external" in "customize view".
Another solution would be using the Package Explorer view.
In Eclipse Luna:
For hiding *.jar select Libraries from external.

Works for eclipse 3 and 4 in the project explorer and package explorer views.
Hey here is how it works:
There you go.
On Juno, see the "View menu" button on the left of the Project Explorer minimize button. Develop the menu and select the "Customize view" option. In the Filter tab, check the "Libraries from external" option. That's all.
