Mark as done is a free Chrome extension developed by mark-as-done Extension. It falls under the category of Browsers and the subcategory of Add-ons & Tools. This extension allows users to easily track the reading status of any page by automatically highlighting links on the original website.

With Mark as done, users can keep track of their reading progress for large documentations or books. The extension automatically marks links as read or unread, making it convenient for users to know which pages they have already read. This feature is especially useful for those who frequently read online articles or study materials.

The latest release, version 3.0.0, introduces a redesigned popup and adds a search feature. The update also includes a breaking change where the "started" status has been removed. Existing starting entries are automatically merged with the "todo" (unread) status. As there are now only two statuses, "todo" (unread) and "done" (read), the configuration options have also been removed.

Mark as done is a valuable tool for anyone who wants to keep track of their reading progress and easily manage their online reading materials. It is a user-friendly extension that enhances the reading experience for Chrome users.
