One of the main features of Pretty Bonnie is the addition of a list of tests at the top of the page. These tests are color-coded based on their status, with green indicating a pass, yellow indicating a partial pass, and red indicating a fail. This allows users to quickly identify the overall status of their tests.

Furthermore, Pretty Bonnie provides the ability to expand each test to view individual consoles and return codes in a readable fashion. This makes it easier for users to understand the specific details of each test and identify any issues that need to be addressed.

Overall, Pretty Bonnie is a valuable add-on for students and developers using the Bonnie platform. It improves the user experience by making the output more visually appealing and providing detailed information about test results.
