The Manager is a skinnable feature-packed tool for admin users. You can add extra users and limit what functions they can access. MODx's Manager makes creating content and managing templates and reusable elements easy. Modules can be added to work with other datasets or make management tasks easier.
The QuickEdit bar lets manager users edit content whilst browsing the site. Most content fields and template variables can be edited quickly and easily.
Custom data entry is easy to code using the MODx API - so you can design forms and collect whatever information you need.
