Eclipse and PyDev Package explorer

[king kikapu]

Hi,

i am trying to "fit" Eclipse/Pydev in my needs/preference, so i want
to ask this:

As it is now, i see all my projects in that TreeView (PyDev Package
Explorer). I would rather want this to behave like a more "normal" IDE
where you Open one project and if you want close it and Open another,
just one at a time and not a TreeView with ALL your projects loaded in
every time you open the IDE.

Is there a way to accomplish thiks in Eclipse/Pydev ??
