Webuzo Unmark (ID : 609) package has been updated to version 2020.2. Unmark is designed to help you actually do something with your bookmarks, rather than just hoard them. A simple layout puts the focus on your task at hand and friendly reminders keep you in line. Filtering options let you find what you're looking for.
