Feature Request: More granular permissions for agents

We would like to see more granular control over agent permissions. Currently, the roles are quite broad, and we have a need to restrict certain agents from accessing specific views or editing certain ticket fields. For example, we want our Tier 1 support agents to be able to view all tickets but only be able to edit the 'Status' and 'Priority' fields. This would help us enforce our internal workflows and prevent accidental changes to sensitive ticket information. A more flexible, role-based access control (RBAC) system would be a huge improvement for managing a large and tiered support team.
