Since my lacking time for this is unlikely to get better soon, I ceased development of this module. If you'd like to take over (or fund the required time), drop a line!
This module extends Drupal's built-in comment functions with the following features and config options, each one per node type:
Improved page title on reply and quote form pages.
User-friendly, thread-specific comment IDs like you know them from most other blog systems (#1, #2, #2.1). This feature is inspired by http://drupal.org/project/comment_easy_reply and was originally requested by neRok - Thanks!
A true comment permalink function similar to and even better than the one shipped with Drupal 7. While the path http://basepath/comment/id simply calls the related node page in D7, the improved comment menu callback in comment_plus redirects to http://basepath/node/nodeID?page=pagenum#comment-commentID and thus even avoids SEO punishment for duplicate content while also jumping to the related comment anchor.
Set a minimum character or word count for comments.
(Instant) replying to a node or comment optionally creates a @username#userid tag which can be processed by the included in-reply-to format filter and will then link to the referring node or comment.
Comment subject fields may be configured as required.
Subject defaults may be configured per node type, including prefixes like Re:.
Comment link titles may be changed per node type, you may e.g. have a label reply instead of add comment for forum posts.
Basic wysiwyg support.
The included comment_plus_js module additionally enables AJAX based instant replies for node types with the comment form on the node view page.
Usually people use one of the WYSIWYG editors for adding/editing content on the websites. But they are not very easy to use for many of them in some cases. If you ever wondered how to put the content on the page formatted in some fancy way (something like two columns of text, for instance) without much burden, and if you don't know how to do that in you editor, feel free to try this module.
At the moment Layouter has an integration with CKEditor and TinyMCE editors (installed in combination with WYSIWYG module), and support for other popular editors will be added soon. But actually you don't necessarily need to have any of these editors installed in order to use Layouter.
Note for developers
Since 7.x-1.1 version you are not limited to the layouts declared in the module, and you can implement custom layouts of your own by creating an extension module. See Layouter Extension Example module for details (you'll find it in modules/layouter_extension_example sub-directory).
