+## Small userscript to browse danger/u/ more efficiently, based on lainmod
+
+It keeps track of how many replies a post has, and shows the number of new replies in red when there are new ones. It marks a post as fully read when you click on it in the list.
+
+It will also show deleted posts, and if you had seen the post before it was deleted it will tell you the title.
