Features:

• Shows PageRank for watever website you are on. It gets the pagerank from google's own servers and it caches the results on your computer and retries if it fails to get it so that you'll always get it as fast as possible.
  
• Shows aggregated comments from a bunch of different sites such as delicious, stumbleupon, wot, alexa, etc.
