Interface Overview - Mastering phpMyAdmin 2.11 for Effective MySQL Management - page 46

Here we have chosen the mysql database:
Clicking on the database name opens the right panel in the Database view, and
clicking on a table name opens the right panel in the Table view. (See the Right Panel
section for details.)
Tree Display of Database Names
A user might be allowed to work on a single database, for example marc . Some
system administrators offer a more flexible scheme by allowing user marc to create
many databases, provided their names all start with marc —like marc_airline
and marc_car . In this situation, the left panel can be set to display a tree of these
database names.
