froog,

Great module you've created! One question though: I have set up all simplify permissions for a group, and would like to reuse this simplify config for other sites as well. is it possible to define a default simplify config in e.g. _config.php?

You can create a simple setup module to create the necessary simplify permissions when you are setting up the site.

setup/_config.php:

<?php

Director::addRules(100, array(
        'admin/setup/$Action/$ID' => 'SetupCMS',
));

setup/code/SetupCMS.php:

<?php

class SetupCMS extends Controller {

    static $url_segment = 'simplify';

    static $allowed_actions = array(
        'simplify'
    );

    function simplify() {
        if (!Member::currentUser()->isAdmin()) {
            return Security::permissionFailure($this);
        }

        // GroupID => Code
        $general_permissions = array(
            1 => array(
                "SIMPLIFY_HIDE_HELP",
                "SIMPLIFY_HIDE_VERSION",
                "SIMPLIFY_HIDE_NON_EDIT_PAGES",
                "SIMPLIFY_HIDE_CREATE",
                "SIMPLIFY_HIDE_SEARCH",
                "SIMPLIFY_HIDE_BATCH_ACTIONS",
                "SIMPLIFY_SHOW_CREATE_OPEN",
                "SIMPLIFY_HIDE_TREE_OPTIONS",
                "SIMPLIFY_DRAGGABLE_ON",
                "SIMPLIFY_HIDE_DRAGGABLE",
            ),
        );

        // GroupID => array(HidePage, HideName, HideType)
        $page_permissions = array(
            1 => array(
                array('Page', 'Behaviour', 'Tab'),
                array('Page', 'Access', 'Tab'),
                array('BlogEntry', 'Behaviour', 'Tab'),
                array('BlogEntry', 'Access', 'Tab'),
            ),
        );

        foreach ($general_permissions as $groupID => $codes) {
            foreach ($codes as $code) {
                $perm = DataObject::get_one("Permission", "Code='{$code}' AND GroupID={$groupID}");
                if (!$perm) {
                    Permission::grant($groupID, $code);
                }
            }
        }

        foreach ($page_permissions as $groupID => $permissions) {
            foreach ($permissions as $permission) {
                $perm = SimplifyPermission::checkField($permission[0], $permission[1], $permission[2], $groupID);
                if (!$perm) {
                    $perm = new SimplifyPermission;
                    $perm->HidePage = $permission[0];
                    $perm->HideName = $permission[1];
                    $perm->HideType = $permission[2];
                    $perm->GroupID = $groupID;
                    $perm->write();
                }
            }
        }

        echo "Simplify settings updated. Simplify rocks!";
    }

}

After that, just access the url /admin/setup/simplify

For a list of simplify permission in the $general_permissions array, you can refer to simplify/code/SimplifyPermissionProvider.php
For a list of simplify permission in the $page_permissions array, you will need to refer to the "Field Tree" after you click on the "Load Field Tree" button in the Simplify interface.

Thanks!!!
