The developer perspective was used in previous versions of PageSeeder. From PageSeeder 5.9, use the developer mode to enable tools dedicated to developers in the user interface.
Selecting the developer perspective exposes the developer tab, the developer action icons and the performance block. It can be selected by holding the cursor over the perspective icon underneath the user name in the top left corner of the interface.
The icons in the developer perspective allow the user to see the interface expressed as XML instead of HTML or see how the document has been stored in the full text index.
