When you visit the plugin’s settings-page, you will find five tabs:

URL-Check will show a list of all your bookmarks. Here you can check, if you have supplied all necessary URLs for your bookmarks.

News will display a sneak-peek to two of my

Help contains some links to other resources, such as the page you are currently reading
