Pages ’09 v4.3, Numbers 2.3 on Mountain Lion.
It is Apple continuing to experiment with interface design. In the latest versions, Apple has removed “open recent” and “open an existing file,” from the Template Chooser panel. There is no user configurable setting to restore these items that were part of the program design.
With the Template Chooser open, you can still access the open recent menu from Pages > File menu. If you want to open an existing file, you can press command+O, and this brings up the File chooser that enables you to navigate to that existing file.
