FocusManga is a free Chrome add-on developed by shylux. It falls under the category of Browsers and is specifically listed under the subcategory of Add-ons & Tools. This program aims to enhance the manga reading experience by adding a diashow (slideshow) function to online manga sites.

With FocusManga, users can enjoy a hands-free reading experience as they browse through their favorite manga. The diashow function automatically flips through the pages, allowing readers to immerse themselves in the story without having to manually click through each page. This feature is especially convenient for users who prefer a more streamlined and uninterrupted reading experience.

In addition to the diashow function, FocusManga also offers an offline version where users can view local manga files. This means that manga enthusiasts can continue their reading even when they don't have an internet connection.

FocusManga supports most major manga sites, ensuring compatibility with a wide range of platforms. The complete list of supported sites can be found on the developer's GitHub page. If your preferred manga site is not on the list, the developer encourages users to contact them to have it added.

Overall, FocusManga is a useful Chrome add-on for manga lovers who want to enhance their reading experience with a diashow function and enjoy offline manga viewing.
