Tracks and syncs your last reading position on Twitter/X, with manual and automatic options. Ideal for keeping track of new posts without losing your place. Uses Tweet ID for precise positioning and supports reposts.
This Tampermonkey userscript helps you track and synchronize your last reading position on Twitter/X (formerly Twitter). It ensures you never lose your place in your timeline, even when new posts appear. The script uses precise Tweet IDs for positioning and fully supports reposts, making it ideal for heavy users who want to seamlessly resume reading.
How it Works: The script monitors scrolls, DOM changes, and focus events to detect new posts. It uses MutationObserver for real-time updates and IntersectionObserver for efficient post detection during searches. Positions are stored per account and can be exported/imported as JSON for cross-device sync.
Compatibility: Works on x.com/* (Twitter/X). Requires Tampermonkey or similar userscript manager.
