Get a project in IDEA 7. In project tree expand some source roots and packages.
Open this project in IDEA 8. See that project tree view has forgotten all expanded packages.
Probably the reason is changed format of ProjectPane component data in iws. In 7 it is:

  <component name="ProjectPane">
    <subPane>
      <PATH>
        <PATH_ELEMENT>
          <option name="myItemId" value="garb21-crs" />
          <option name="myItemType" value="com.intellij.ide.projectView.impl.nodes.ProjectViewProjectNode" />
        </PATH_ELEMENT>
        <PATH_ELEMENT>
          <option name="myItemId" value="java-a" />
          <option name="myItemType" value="com.intellij.ide.projectView.impl.nodes.ProjectViewModuleNode" />
        </PATH_ELEMENT>
        <PATH_ELEMENT>
          <option name="myItemId" value="PsiDirectory:C:\uf\Alexander.Chernikov\work\iprojs-6.5\garb21-crs\java-a" />
          <option name="myItemType" value="com.intellij.ide.projectView.impl.nodes.PsiDirectoryNode" />
        </PATH_ELEMENT>
        <PATH_ELEMENT>
          <option name="myItemId" value="PsiDirectory:C:\uf\Alexander.Chernikov\work\iprojs-6.5\garb21-crs\java-a\coverage" />
          <option name="myItemType" value="com.intellij.ide.projectView.impl.nodes.PsiDirectoryNode" />
        </PATH_ELEMENT>
        <PATH_ELEMENT>
          <option name="myItemId" value="PsiDirectory:C:\uf\Alexander.Chernikov\work\iprojs-6.5\garb21-crs\java-a\coverage\lab" />
          <option name="myItemType" value="com.intellij.ide.projectView.impl.nodes.PsiDirectoryNode" />
        </PATH_ELEMENT>
      </PATH>
    </subPane>
  </component>

In 8 it is:

  <component name="ProjectPane">
    <subPane>
      <PATH>
        <PATH_ELEMENT>
          <option name="myItemId" value="garb21-crs" />
          <option name="myItemType" value="com.intellij.ide.projectView.impl.nodes.ProjectViewProjectNode" />
        </PATH_ELEMENT>
        <PATH_ELEMENT>
          <option name="myItemId" value="java-a" />
          <option name="myItemType" value="com.intellij.ide.projectView.impl.nodes.ProjectViewModuleNode" />
        </PATH_ELEMENT>
        <PATH_ELEMENT>
          <option name="myItemId" value="java-a" />
          <option name="myItemType" value="com.intellij.ide.projectView.impl.nodes.PsiDirectoryNode" />
        </PATH_ELEMENT>
        <PATH_ELEMENT>
          <option name="myItemId" value="coverage" />
          <option name="myItemType" value="com.intellij.ide.projectView.impl.nodes.PsiDirectoryNode" />
        </PATH_ELEMENT>
        <PATH_ELEMENT>
          <option name="myItemId" value="lab" />
          <option name="myItemType" value="com.intellij.ide.projectView.impl.nodes.PsiDirectoryNode" />
        </PATH_ELEMENT>
      </PATH>
    </subPane>
  </component>

Minor priority: this will constantly affect only ones who will switch between 7 and 8 with the same project.
