GitHub has introduced an integrated issue tracking system, accessible via an "Issues" tab on repository pages, offering features similar to managing emails, such as a fast JavaScript interface and the ability to create and apply labels for user assignment or categorization. Users can also drag and drop issues to prioritize them, vote on issues, search, sort, and filter issues, and even close issues through commit messages. The system includes keyboard shortcuts for efficiency, and for those using a different issue tracker, the feature can be disabled in the repository's "Admin" tab under "Features."
