Improving Drupal's page loading performance
Views Slideshow can be used to create a slideshow of any content (not just images) that can appear in a View. Powered by jQuery, it is heavily customizable: you may choose slideshow settings for each View you create.
The teaser by content type module allows an admin to set a different teaser length for each content type. Note that as with the site-wide setting, this only affects new posts or new edits of posts.
Editview is a plugin for the Views module. It allows you to create a view in which the nodes are editable, and new nodes can be created. Editview uses AJAX to speed things up, but will still work on browsers with javascript disabled.
This module provides a new view style which lets you assign taxonomy terms to the nodes in the view. Use this to quickly add tags to a group of images or other content.
A mass category editor. Allows any nodes shown on admin/content/node to have terms added or removed in bulk, using the normal 'node operations' selector. Also provides a tab to view/edit all nodes terms individually.
This module augments Views by allowing bulk operations to be executed on the nodes displayed by a view. It does so by showing a checkbox in front of each node, and adding a select box containing operations that can be applied on the selected nodes.
The module processes feed items immediately after parsing and retains only these feed items that match some user-defined filtering criteria.
The Faceted Search module provides a search API and a search interface for allowing users to browse content in such a way that they can rapidly get acquainted with the scope and nature of the content, and never feel lost in the data. More than a search interface, this is an information navigation and discovery tool.
This module allows form elements generated by the taxonomy module (selects, multi-selects, autocompletes, etc. for selecting terms) to be rearranged individually throughout the node form.
