The "Bookmarks Manager and Viewer" extension offers a comprehensive panel view, designed to facilitate modification of your bookmarks. The panel comes equipped with a fuzzy search feature, similar to Google search, allowing you to locate matching bookmarks with ease. The extension provides a versatile set of tools, enabling on-the-fly editing of bookmarks. Not only can you rearrange bookmarks by dragging them to new positions in the tree, but you can also create new directories and seamlessly organize bookmarks within them.

1. Fuzzy Search: Find matching bookmarks, even when uncertain about the exact title or URL.
2. Validation Button: Identify and manage broken or duplicated bookmarks recursively.
3. Edit Properties: Modify the title or address of a bookmark directly from the panel.
4. Toolbar Color: Quickly discern if the current page is bookmarked by observing the color of the action button.
5. Sort Bookmarks: Arrange bookmarks alphabetically for enhanced organization.
6. Supports Live Bookmarks: Explore dynamic content (RSS feeds) within bookmarks.
7. Opening Mode: Choose between opening bookmarks in a browser tab or a popup view.
8. Keyboard Navigation and Operation: Use keyboard shortcuts for efficient navigation and operation within the extension.
