Most JBoss projects Confluence documentation, notably Arquillian, can be exported to PDF which is very handy for offline browsing and archive :

1. Click Tools > View in Hierarchy
2. Click Advanced tab
3. Click "Export to PDF"

However, this feature is missing in the JBoss AS7 Confluence Space. It would be awesome if this is enabled, as JBoss AS7 is the flagship product of JBoss. This feature should also have a more prominent introduction, as people unfamiliar with Confluence unaware of this very useful feature.
