Standard URL for page types
It would be nice when browsing a page to have a standard URL for that page with a describer at the end that you can exchange to view a different group of data. (i.e. http://trackvia.com/blah/blah/Page3). Exchanging "Page3" with "Page4" would give you the same layout but with the next group of data. This way it would be easy to create shortcuts for groups of data that you frequent.
