Wanda (New Tab changer) is a unique Chrome extension designed to replace the standard new tab page with a thought-provoking reminder of life's impermanence. Upon opening a new tab, users are greeted with the stark message "One day you'll die," prompting reflection on mortality and the importance of making the most of one's time. This extension encourages users to prioritize meaningful activities and live consciously by confronting the fleeting nature of existence.

In addition to the central message, Wanda may feature a real-time counter or age calculator, allowing users to visualize the passage of time or their current age. This can enhance the experience by providing personal metrics that reinforce the theme of mortality. The design can range from minimalist text to a more interactive interface, making it a versatile tool for those seeking a blend of dark humor, existential reflection, and mindfulness within their daily browsing experience.
