To make the environment feel like a functional desktop rather than just a stylized landing page, I built two new core applications into the system dock: a working Calculator utility and a dedicated “About Me” panel. For the calculator, instead of relying on basic, insecure evaluation tools, I structured an inline string compiler using strict execution rules to handle chained arithmetic expressions smoothly, mapping the interface out onto a clean button matrix. Alongside it, the “About Me” window serves as the primary personalization node for the OS, using custom CSS flex badges to cleanly highlight my background. Everything is feeling incredibly cohesive now.
