18954	Automatically whitelist screen options added via add_screen_option()	mdawaffe		"{{{set_screen_options()}}} currently maintains a hardcoded whitelist of screens that can set options.

The list is extendable via the filter:

{{{
apply_filters('set-screen-option', false, $option, $value);
}}}

but that's sort of a pain.  If a plugin calls {{{add_screen_option()}}}, it should be added to the whitelist automatically.

Also note that {{{set_screen_options()}}} is called so early, there's no convenient place for plugins to add to the {{{set-screen-option}}} filter.  The best workaround I've been able to come up with is to manually call {{{set_screen_options()}}} again inside the page's {{{load-$hook}}}.

Example naive plugin code that does not work in <=3.3.

{{{
# Inside a menu page's load-$hook
// Display per-page settings in screen options
add_screen_option( 'per_page', array( 'label' => __( 'Things' ) ) );
}}}"	enhancement	new	normal	Future Release	General		normal		3.4-early	Ken@…
