About URL Scheme Opener

URL Scheme Opener: High-Precision Browsing Automation Assistant [What's New in v1.1.5] * Improved Stability & Heavy Load Handling: Resolved issues where browser alarms could trigger late under heavy PC load or sleep recovery, causing schedules to be skipped. Implemented target time persistence in alarm names, direct bypass for near/passed triggers, and a robust startup handshake (offscreenReady) with the precision timer. [What's New in v1.1.3] * Fixed Critical Issue: Resolved a bug where the high-precision timer (Offscreen Document) failed to start due to a script loading error. This fix ensures that scheduled URLs open accurately at the intended time. [What's New in v1.1.2] * New "Open in Background" Mode: You can now choose to open URLs without stealing your current focus, allowing you to continue your work uninterrupted. [What's New in v1.1.0] * High-Precision Timer: Overcomes browser alarm delays using Offscreen Documents. It now opens URLs with millisecond-to-second accuracy by pre-calculating the exact moment to trigger. * Flexible Sync Settings: Choose whether to sync schedules across all your devices or keep them strictly local to a specific PC. * Core Engine Optimization: Major refactoring for improved stability and performance. [Earlier Updates] * Dark Mode Support. * Improved UI usability and table layout. Tired of manually opening the same links every day, week, or month? URL Scheme Opener empowers you to automate your workflow by scheduling any URL or URI scheme to open exactly when you need it. Beyond simple web links, this extension can trigger system-level actions or launch specific applications via their registered URI schemes (e.g., mailto:, ms-settings:, zoommtg://, vscode://). Key Features: * Extreme Accuracy: Leverages modern browser technologies to ensure your schedules fire exactly on time, even in the background. * Versatile Scheduling: Use powerful cron expressions or intuitive intervals (daily, weekly, yearly, one-time) to fit any routine. * Cloud Sync or Local Only: Seamlessly sync settings across your browser profile, or disable sync to maintain unique schedules for different workstations. * Smart Tab Management: Choose between new tabs or new windows. Automatically focuses on existing tabs to prevent clutter. * Rich Desktop Notifications: Stay informed with custom notification messages. Click a notification to re-open the link anytime. How it Helps You: * Automate Repetitive Tasks: Automatically open meeting URLs, daily report forms, or news sites at set times. * Never Miss a Beat: Get timely reminders for sales, live streams, or recurring system checks. * System-Level Integration: Schedule OS settings or specific apps to launch directly from your browser.
