Here is what I gleaned out of Teresa's PowerPoint:
1. Open the document library where the web part page is stored.
2. In the left nav, go to Modify setting and columns.
3. In the "All Documents" view, add a column named "Title".
4. Go to the "All Documents" view.
5. The new column is filled with a title for each web part page - "Web
Part Page".
6. You can then modify the properties of each item in the library and
give each page a proper name.
Be aware, there are two caveats with this approach.
1. It only works with Smart Pages stored in a Document Library.
2. Changing the Title (or any metadata property) unghosts the page.
