With right-click it will open the preferences window. With central-click it will check if there are any new comics for you to read. With left-click it will open the Comic Aggregator in a new tab in foreground (can be configured to be a background tab).
If there aren't any comics to read the icon will go gray. In other hand, if there are new comics to read, it will go colorful. Also, it will show the number of new comics to read. If anything went wrong it will show a red X.
The notifier will show, with a tooltip, the list of unread comics and the number of unread strips per comic.
