[wp-hackers] trying to understand the Admin API ... changing default values for visible Screen Options

[Tom Ransom]

I can't presume to speak for the core team. And I need to clarify -  
the checkbox that are set within the Screen Options do persist - but  
the visibility of the Screen Options area doesn't.

I'd suggest that the thought was - it isn't something that you'd  
change often after you get it setup to your preferred layout.

The checkboxes persist from session to session and are managed as an  
option -
take a look in wp-admin/includes/template.php

function get_hidden_columns($page) {
	$page = str_replace('.php', '', $page);
	return (array) get_user_option( 'manage-' . $page . '-columns- 
hidden', 0, false );
}
