Alter Fields Pro
For each custom field, you can enable its display in backend item list with some handy settings like CSS classes for table column heading and data cell, field layout (except frontend templates overrides).
Support display of custom fields for Joomla articles, users, contacts and categories by default.
Its possible to allow table ordering by custom field values, add the filter for custom field in Joomla search tools and search by custom field value via common search tools search field.
It's also possible to limit access to custom field for specific usergrops in backend item edit pages (currently, Joomla always displays all custom fields for administrators).
Works with 3rd-party Joomla extensions if they follow native Joomla code standards (but no guarantees).
