This one allows you to save links for reading later. Also improved the new links preview.
Biggest change is how the blacklister works. It's more like a style rule engine now. You supply a regex, and all links that match that regex will get that style. If you omit a style, the link is hidden (blacklisted).
As an example, here is my current rule setup:
paulbuchheit|gaborcselle->background-color:#FFFF00;
Ask HN->background-color:#00FFFF;
codinghorror.com
The part before the '->' is the regex, the part after is the style. These three rules highlight certain links, and blacklist codinghorror.com links.Let me know what bugs you encounter, if any.
