There is no way to tag a docs
Users have more and more document and ca be lost to overview all the documents related to one thematic.

Describe the solution you'd like
It could be great to have somme "Tag" / "Catégory" that we could add to a document
For exemple Docs 1, 5 and 11 are tagged with the word "UX", and Docs 4,7 are tagged with the words "Impovement" and "RGAA".
Then the personn who have acces to all of these Documents could eeasily see the "tagsor "categories" under (or on the side) all of these documents.

And an filter menu on the left will make appears all the tags, so the reader could click on one of this tags in order to make appears only the documents related to this tag
