Trac Code Comments Plugin
This plugin allows you to leave comments on top of files, changesets, and attachments. Once you've added all of your comments, you can send them to tickets. These include links to these comments and their description.
The problem that this plugin solves, is two-fold. When reviewing code, it's difficult to associate your comments with their appropriate context. Then, collecting all of these new issues into actionable tickets requires typically a lot of manual effort.
More information on installation and configuration can be found in the README.
