This module allows you to filter or sort terms according to their hierarchical order or hierarchical depth.

Use cases

You need to display a list of entities ordered by their taxonomy terms in hierarchical order, example, a list of products ordered by categories.
You need to display a list of entities where their terms is on a particular depth
You need to display a list of entities in a select box with Better Jump Menu and you need it sorted hierarchically.

Two Views sort handlers (fields): Hierarchy weight and depth, with field, sort and filter handler.
If Entity Menu Links is installed, you'll be able to access to the hierarchical weight of a menu item.

Entity Menu Links: Use your menu links in Views.
Better Jump Menu: Display any entity in a select box.
Views Term Hierarchy: This module provides a views field and compute the value of the hierarchical order on the go. It doesn't use the database to get the data and it won't work when doing views relationships.
Taxonomy Entity Index: this module maintains a normalized index of all terms associated with a specific entity and revision. The core {taxonomy_index} table only maintains its data for published nodes but this maintains its data for all entity types (regardless of published or not) and also indexed by revision. Very useful if you want to sort by hierarchy other kind of entity like Users or something else.
Taxonomy Lineage: Less or more the same purpose for D6 with a development version for D7.
Views Tree: This module provides a tree-based style plugin for Views.
