Contribution and approach
I built the application around a modular WPF architecture and event-driven state flow; the capsule uses minimal resources while idle and expands contextually to surface the relevant tool. I integrated Windows SMTC media controls, NAudio volume and microphone monitoring, global shortcuts, multi-monitor placement, and fullscreen game detection. Spotify and Google Calendar OAuth sessions are protected locally with DPAPI, while favorite apps, PowerShell commands, and Gaming/Personal/Work modes provide guarded desktop automations.
