WebAssign Plus is a Chrome extension designed to improve the user experience on the WebAssign practice problem platform, particularly for AP Physics students. This free add-on introduces several quality of life enhancements that streamline the workflow for users tackling complex mathematical problems. Key features include the ability to submit questions using the enter key, enabling a more efficient interaction without the need to click the submit button. Additionally, it offers a live KaTeX preview for mathematical expressions, eliminating the hassle of opening a separate preview window.

Other notable improvements include automatic focus on text fields post-submission, allowing users to continue working seamlessly without extra clicks. The extension also provides instant scrolling after submissions, enhancing navigation through the problem sets. Users can disable the 'Enter...' tooltips that appear below text fields for a cleaner interface. However, it is important to note that this extension is specifically tested for AP Physics, and any issues can be addressed by disabling the extension or reporting them on GitHub.
