Hi,

Odoo doesn't natively offer "read/unread" tracking for documents. Consider using Odoo's Approval app to create a workflow where users must "approve" documents after review, providing a similar level of accountability.

Custom development is an option, involving adding a "read" status field to the document model, modifying access logic to record when a user opens a file, and creating a UI to display unread documents. Alternatively, explore integrations with third-party document management systems that offer advanced tracking features. If custom development is chosen, it requires modifying the document model, overriding access methods, and building a user interface to display unread documents.

Hope it helps
