This is probably a good idea … I am tied up with sad family matters at present, but once I am back on the case I will add a check box to the settings page to disable loading of the default skins CSS file.
In the meantime, a solution may be to add something along the lines of the following to the functions.php file of your theme (or child theme):
add_action( 'wp_enqueue_scripts', 'remove_cc_skins_stylesheet', 20 );
function remove_cc_skins_stylesheet() {
wp_dequeue_style( 'ccchildpagesskincss' );
wp_deregister_style( 'ccchildpagesskincss' );
}
This should dequeue the CSS for the skins but leave the layout CSS in place and untouched.
I hope that this helps.
I have released a new version of the plugin which includes an option not to load the skins CSS in the Settings->CC Child Pages options.
