New application profiling recommendation   When you use the Application Profiling Wizard to check the overall performance of your database based on its schema, the wizard checks the order of columns in tables. The wizard makes recommendations when the majority of wide columns precede the narrow columns. Ordering columns so that wider columns precede narrow columns can negatively impact response times. Narrow columns should be defined in the table declaration before wider columns, unless they are accessed infrequently.

Wide columns are columns greater than 15 bytes in size, or LONG data types (for example, LONG VARCHAR), or columns defined as XML. See Review the order of columns in tables.

Enhancements to how user permissions are managed and displayed   Numerous enhancements have been made to the way user permissions are displayed in the plug-in. It is easier to view and change the permissions that have been explicitly set for a database object. When you select a database object, the permission information now appears in a tab in the right pane. Column permissions are displayed with their corresponding table permissions. See Grant permissions to users.
