ONE DAY PLANNING - Visual Daily Scheduler & Pomodoro Timer Design your ideal day with intuitive drag-and-drop and a professional floating timer. [WHAT'S NEW IN v2.2.0] ● Significant Performance Optimization (Highest Impact) Achieved a dramatic reduction in CPU usage (down to ~1-2%) through complete component memoization and context-aware timer updates. The app is now incredibly lightweight even when running the timer. ● Reliable Service Worker & Stability Resolved critical issues with Service Worker registration and initialization. The extension icon and background processes now work reliably after updates. ● Intelligent PiP & Alert Management PiP windows now handle alerts internally to prevent redundant mini-windows. Added a "Manual Pause Respect" logic in Auto Mode—the timer won't auto-restart if you've intentionally paused it. ● Precision Current-Time Line The red indicator on the schedule now updates smoothly with second-level accuracy, perfectly synchronized across all zoom levels. --- DETAILED DESCRIPTION "Manage your daily schedule more casually and more beautifully." One Day Planning is a high-end scheduling tool designed for professionals and students who value their time and visual environment. Forget tiny extension pop-ups.

Most tools rely on cloud storage, but that means "entrusting" your precious data to external servers. Your business projects, confidential schedules, and private routines—are they safe out there? One Day Planning keeps 100% of your data within your browser. No external servers, no cloud syncing, and no tracking. We provide the ultimate peace of mind for professionals who prioritize security and compliance. ● Intuitive Drag & Drop Planning feels like a game. Add, move, and stretch tasks with smooth mouse movements. Assemble your day like a puzzle. ● Background Automation Set your routines by day of the week, and they will automatically appear. The extension handles task transitions in the background, keeping you on track even when the browser tab is closed. ● Professional Floating Timer (PiP) Keep your task name and countdown always visible on top of other apps. Perfectly synchronized with millisecond precision to end exactly at the scheduled :00 second mark. DESIGN PHILOSOPHY As a premium UI/UX experience, we've eliminated outdated "black borders" and unified all corners to a consistent 10px radius. The result is a modern, "alive" interface that feels like a native OS feature. Start planning your next productive day with One Day Planning.
