Role Permissions Filter

Managing role permissions in Drupal can become overwhelming very quickly.
On medium or large sites, the permissions page often contains hundreds of options,
making it hard to understand what a role actually has enabled.

Role Permissions Filter solves this problem by adding a simple but powerful
UI enhancement to the role permissions page.
It introduces an "Only show checked" toggle that allows administrators
to instantly hide all unchecked permissions and focus only on what is active.

Features

• Adds an "Only show checked" checkbox to role permission pages.
• Instantly hides unchecked permissions for easier review.
• Works alongside Drupal’s built-in permission filter.
• Remembers the toggle state per role using the browser (localStorage).
• UI-only behavior — no changes to stored permissions or database.

Post-installation

After enabling the module, visit any role permissions page:
/admin/people/permissions/ROLE_NAME.

You will see a new "Only show checked" toggle near the permission filter.
Enable it to display only the permissions that are currently active for that role.

Additional requirements

This module has no requirements beyond Drupal core.
It uses a small JavaScript behavior to enhance the existing permissions UI.

Recommended modules/libraries

None.
This module is designed to be lightweight and work out of the box with Drupal core.
