🖥️ Devlog #7: Dual-Pane Start Menu & Calculator

I built a dual-pane Windows 11 style Start Menu. The left pane holds pinned apps and recommended files, while the right pane has a mobile link settings configuration for Android and iOS devices. I also built a glassmorphic floating calculator with click sounds and clear operations, and updated the taskbar icons to show an active neon dot whenever an application window is open.
