Documents - Forbidden Delete
In standard-ODOO you can first archive and then delete documents inside the documents-app. This small addition prevents you from deleting documents, it is not possible anymore.
Documents - Partnerenrichment
When importing or creating a bill/invoice inside the documents app, the partner is not added to the document-tags automatically. Therefore you can not search for the partner inside the document-app. This app closes the gap and allows you to filter/search for partners inside the documents app.
You import a bill inside the documents app. You validate and book the bill. The moment the bill is booked, the partner/supplier is known! With this app, the parter is attached also to the document.
