LPlus/CAT Optimizer is a Chrome extension developed by mfermor that adds useful features to the LPlus/CAT platform. With this extension, users can now enhance their LPlus/CAT experience by utilizing additional functionalities.

One of the key features of LPlus/CAT Optimizer is the ability to navigate LPlus/CAT using the keyboard. Users can now easily select answers using the keyboard, mark questions with the Num-Pad + key, and verify answers with the ENTER key. Additionally, users can navigate through questions using the arrow keys and automatically skip the re-display of questions that have been correctly answered.

Furthermore, LPlus/CAT Optimizer improves the overall user experience by providing a progress indicator for the results and optimizing the tab order. However, it should be noted that the tab order optimization may not always work as expected.

For users who desire more functionalities, the developer, mfermor, invites them to contact directly for further inquiries.

To access the user guide, simply click on the LP symbol in the browser's address bar.

Excitingly, LPlus/CAT Optimizer now also supports the CAT platform, expanding its usefulness to a wider range of users.
