Version 1.15 update: Added Nocturne support for auto-link. Also updated the way auto-link gets the list of cards so that in the future, adding new cards won't require a new update to the extension. Fixed bugs with rollover images for cards such as Horn Of Plenty, Salt The Earth, etc. Made it so that "Inherited" auto-links to "Inheritance" just for fun.
This version has been submitted to Firefox for review, so hopefully it will be public really soon. I don't even know how the update process works for Firefox; hopefully it will just automatically detect an update?
*Edit* Oh cool, reviewed and approved already!
