With this extension, you can remove the tournament board, allowing you to focus solely on your language learning without distractions. It also adds shortcuts to make practicing more efficient, such as the ability to press numbers 1 to 9 to select options for answering questions. Additionally, you can use the shortcut Alt + Shift + P to quickly navigate to the practice section.

However, it's important to note that this extension may make your learning more challenging. It removes hints, requiring you to rely solely on your knowledge and memory.
