 # 02 · Snippet Library
 
-The Snippet Library is the left pane and the primary entry point to the app. A **snippet** is a saved Vega-Lite specification together with metadata (name, comment, timestamps, tags, references to external datasets). The library lets the user browse, search, sort, select, and manage their snippets. Editing the specification, the draft-vs-published workflow, the live preview, and dataset management are covered elsewhere (see *Spec Editor & Draft/Published Workflow*, *Live Preview*, *Datasets*); this section covers only the library and management surface.

 ## The List
 
 The list shows every saved snippet and is always visible. A persistent "Create New Snippet" affordance sits at the top of the list, above all snippets, so the user can always start a new snippet regardless of scroll position.
 
-- The list shows all snippets, ordered newest-modified first by default (see *Sort*).
-- A "Create New Snippet" item is pinned at the top of the list; activating it creates and selects a new snippet (see *Snippet Operations*).
-- Selecting a snippet makes it the **active snippet**: it loads into the editor and preview, becomes highlighted in the list, and the URL updates to reflect the selected snippet so the state is shareable and survives a page reload (see *Application Shell & Navigation*).

 - **Duplicate**: creates an independent copy of the active snippet with a name suffixed "(copy)". The copy carries over the specification, comment, tags, and dataset references, gets fresh created/modified timestamps and a new identity, and becomes the active snippet. A success toast confirms the duplication.
 - **Delete**: permanently removes the active snippet after the user confirms a warning that the action cannot be undone. After deletion no snippet is active. A toast confirms the deletion.

 New snippets get a sensible default name, and a tag field exists on each snippet for categorization, though tags are not a primary user surface.
 
 - A new snippet receives an auto-generated default name based on the current date and time, so it is uniquely identifiable until the user renames it (renaming happens in the metadata panel).

 ## Storage Monitor
 
-A small indicator at the bottom of the library shows how much of the snippet storage budget is in use, warning the user before they run out of room. This concerns snippet storage specifically; datasets are stored separately with far greater capacity (see *Datasets* / *Data Model*).

 - Displays current usage against the total budget (used vs. total), where the practical snippet budget is about 5 MB.
