Overrides the drupal status messages and give you the ability to choose out of 4 themes.

A common views task is to display a set of node teasers, filtered and ordered by any condition. However, these filters and orderings are limited to the actual views display in the first place and is lost once a visitor follows the link to one of the result nodes, seeing the actual node page.

If you do not like the existing common approaches (like using fields instead of teaser row style, cloning full node displays into another paged view, manually maintaining book structures or node orderings etc) or if you simply want to extend bookish navigation to any views result containing teasers, VRP may be a remedy.
