 The base class `WP_List_Table` and its extended family is a great addition
 to the WordPress administration API. The `WP_Posts_List_Table` class has
 well-documented filters that support adding custom columns to the default
 table.

 However, custom column support in the `WP_Terms_List_Table` class is
 incomplete. There is a filter in the `column_default` method, but it is
 useless because there is no filter in the `get_columns` method to allow
 expanding the column array.

 Please consider changing the last line of the `get_columns` method to
 something like:

 `return apply_filters( "manage_{$taxonomy}_custom_get_columns", $columns
 );`

 or

 `return apply_filters( "manage_{$taxonomy}_columns", $columns );`

 The affected file is `wp-admin/includes/class-terms-list-table.php`. The
 choice for the filter name depends on whether you want to follow the
 convention used in the `WP_Terms_List_Table` class (first alternative) or
 the convention used in the `WP_Posts_List_Table` class (second
 alternative).

 This one-line change would finish the job of making the default table
 expandable. Thank you for your consideration.
