Bb Doc Viewer+ is a Chrome extension developed by Raj Kundu that aims to enhance the document viewing experience on Blackboard. As an unofficial extension, it provides various improvements specifically designed for viewing documents on the Blackboard platform.

One of the key features of Bb Doc Viewer+ is the addition of an "Open in New Tab" button to Bb-embedded document viewers. This allows users to easily open documents in a separate tab for a better viewing experience. Additionally, the extension enables the use of the Escape key to close Bb panels, providing a convenient way to navigate and close panels without reaching for the mouse.

Another useful functionality of Bb Doc Viewer+ is its ability to automatically maximize Bb files opened in a new window or tab. This ensures that the document is displayed in its full size, making it easier to read and navigate. Additionally, the extension sets the page title to the document filename, allowing users to quickly identify the document they are viewing.

Overall, Bb Doc Viewer+ offers valuable enhancements to Blackboard's document viewing capabilities. While it is important to note that this extension is unofficial and not affiliated with Blackboard, Inc., it provides a useful set of features for users looking to improve their document viewing experience on the platform.
