Administer Tool Tip
The Administer Tool Tip module is a very deluxe backport of the contextual functionality in drupal 7 and adds a lot more. This module is a great way to extend the standard drupal interface by enabling the user to edit, delete and manage nodes, blocks, users etc on the fly. It even creates dragging and dropping of blocks on every page!
The Administer Tool Tip module adds little icons to all entities (node, block, view, user) which are visible on mouseover. You can click on them to open a tool tip where all kinds of functionality exists such as block position settings, links to edit the entity and statistic information.
The module itself can be extended via hooks to add more functionality to each different kind of tip.
