I have released version 0.2 of Fun with In-Context Comments today. This post gives a quick rundown of the changes.
A lof of the changes have been aimed at reducing the code; however, there are also significant user-facing improvements.
The plugin is now easier to install. All of the template tags are now optional. All the features will be added automatically; however, if you want more control over where they are added there are template tags to control where the filter fields (see below) appear and where the options for the commenter will appear.
Significantly, I have written the code in a way that detects when the tags are being used and turns off the automatic inclusion so there are no settings to change if you want to use the template tags.
I have added filter fields. These use jQuery to hide comments that do not match the selected settings, so if you ask your commenters what version of WordPress they are using then anyone visiting the site can choose to show only comments from users, using version 2.5.x of WordPress.
Finally, I have been working with Ronald of Reader Appreciation Project to make this plugin compatible with WP Ajax Edit Comments, so as of version 2.1 of AEC and version 0.2 of this plugin commenters can now edit their choices.
