Comical is a program that lets you know when a webcomic you read has been updated and allows you to download the newest strip. It's great for people who (like me) follow a ton of different webcomics. It currently supports Over five-hundred different web comics. It even supports Newspaper Comics, Alt-Text, and Hidden Panels. If Comical is missing a comic you like, the program comes with the ability to add new comics manually or feel free to post a request for someone else to do it for you on the forums! [more inside]
