## Description

Kyst browser extension is part of our application that enhances your Bluesky experience by providing advanced bookmark management capabilities. It not only lets you bookmark your favorite posts, but also organize, sync, and access them across devices. 

The extension is designed to make the bookmarking experience more seamless and efficient. It adds a bookmarking button to each post, allowing you to save them easily (or to remove them, if marked previously). Then, there's the sidebar, where you can see and manage your bookmarks. The extension automatically syncs your bookmarks with Kyst servers, ensuring they're always up-to-date, across browsers and devices.
