# Managing collections

Rename, delete, browse, and prune collections from the side panel.

## Views

Toggle between the **card view** and the **tree view** from the header. The tree
nests each collection over its bookmarks so you can browse pages without leaving
the list. Clicking a bookmark opens it in a new tab.

## Per-collection actions

- **Card / list:** the **⋮** menu on each row — Rename, Delete, Open collection.
- **Inside a collection:** the **✎** and **🗑** buttons in the header.

## Rename

Opens a dialog pre-filled with the current name and description. Maps to
`PATCH /collections/{id}`.

## Delete

Confirmation dialog showing the collection name and page count. Permanently
removes the collection, its bookmarks, their chunks, and the Chroma collection.
There is no undo.

## Remove a page

The **✕** on a bookmark row removes it from the collection immediately, no
confirmation. Maps to `DELETE /bookmarks/{id}` and also drops that bookmark's
vectors.

## Not supported

Reordering collections, moving a bookmark between collections, bulk remove, and
undo. The tree view is a browsing surface only.
