PaperTodo

PaperTodo is an open-source Windows desktop application that combines sticky notes, task lists, and lightweight productivity tools. Built with native WPF, it displays independent paper-like windows directly on the desktop for quick access. Users can create checklists with drag-and-drop task ordering or write Markdown notes containing formatted text and images. Notes can collapse into compact capsules that dock along screen edges and expand into interactive previews when hovered over. The application supports multiple monitors, scheduled reminders, and customizable themes. Its plugin system extends functionality with clocks, Pomodoro timers, and other desktop utilities. PowerShell script capsules and file linking provide shortcuts to frequently used resources and commands. All notes and associated data remain stored locally, with automatic saving and snapshot backups.
