X Bookmark Tweaks is a Chrome add-on developed by わーるど, offering adjustments and enhancements to the bookmark feature of X (formerly known as Twitter). The add-on aims to improve the user experience by providing features like correcting scroll behavior when expanding bookmarked posts and preventing the screen from flickering when reopening post details.

The main highlight of X Bookmark Tweaks is the scroll correction feature, ensuring that when clicking on a post to view its details, the scroll remains at the same position instead of jumping to the top of the bookmark section. Additionally, the add-on promises more functionalities to be added in future updates, with the source code publicly available on GitHub under the MIT License.
