Advanced Taxonomy Blocks makes use of the JQuery menu module to create extremely customizable blocks for browsing through single hierarchy taxonomies. Though the taxonomy menu module does something similar, if you use this module you will see that they are in fact entirely different in their approach.
Unlike taxonomy menu which directly ties the menus into the Drupal menu system, Advanced Taxonomy Blocks doesn't touch the menu system at all and therefore allows much more flexibility. This module ships with two default blocks: A block with all of the enabled vocabularies displayed by default (this can be customized to show only certain vocabularies) and a Forum block (I went ahead and threw this in since forums are built with taxonomy).
This module displays a customizable message at the bottom of a comment when it has been edited. The message by default is wrapped into a div, but it can be overridden by implementing the theme function theme_comment_edited() in your theme. Also there is a configuration option which forces the module to print this message into the $comment->comment_edited variable instead of the $comment->comment, so you have more freedom in where to place the message.
If you are looking for general comment enhancements, please take a look at the advanced comment module.
Theming
Themers are now able to place the comment edited message elsewhere. For this select the "Use template" option in the configuration page, then in your preprocess function use the $comment->comment_edited property. It contains the themed messages.
A new theme function is responsible to render both of the messages now: theme_comment_edited_messages($messages)
Features
Replace core comment submitted timestamp with the date the comment was created (original behaviour: the timestamp updates with every edit).
Append an "Edited by ... at ..." message when a comment gets edited
