On the Edit Category and New Category windows, the Available Plugins table has a View drop-down list that allows you to manipulate which plugins are displayed in the table.

The drop-down list consists of all defined categories and an initial option that displays all plugins.

To limit the plugins displayed in the Available Plugins table, select a category from the View drop-down list. For example, selecting General System Information changes the available plugins to display only those plugins currently in the General System Information category.

If a plugin is listed in the Selected Plugins table and is in the selected category of the Available Plugins table, it appears in the list but has a line drawn through it. The strike-through indicates that the plugin has already been selected. You cannot include multiple instances of the same plugin in the Selected Plugins table.
