Idea to show the Directory in a full page. Imo if we have this we don't need the left hierarchical document navigator. However, we can have both. They are not incompatible!

Inspirations

Roam Research

In the left menu you can find the All Pages link.

The All Pages has a list with all the documents, mentions dates

Wordpress

Sketches

Any document can be open in the site's directory.

The Site's directory you see all documents with hierarchy. Having the full page space gives a better UX to see more information as number of citations, comments, authors.

It is easier to move or delete documents than the small side left panel ala Notion. Also helps a better navigation to understand the document structure.

Demo Mockup

I vibe coded a version of this feature so y'all can see how it can be. This is a mockup and is not part of the main code yet. if we believe that this is the way it can be done, then we can continue and define better more specifics about it

If you cannot see the video, here are some of the highlights:

you can access the all documents page for a site from the three dot options menu, the same way we do for document versions and directory
it shows all the documents for the site, in a tree, so it respects the hierarchy
you can filter documents by name, change sorting, move, rename, delete and even do all this actions in bulk (by selecting multiple documents
we can consider add pagination if we believe is too heavy for the backend.
