If you use Delicious, then you probably know, that the biggest problem with a wast collection of bookmarks is one's inability to remember, that you have certain bookmarks, so you never take a look into Delicious archives.
ChromeDelicious extension combines your Google results and Delicious bookmark results onto one screen, each time you perform a Google search, so that you never miss your Delicious bookmarks.
And no worries, it does not slow down your Google search for two separate reasons. First, it works after a Google search results are already on your screen. Second, it caches all your Delicious bookmarks on the computer to be available and only calls Delicious once an hour.
So far it is an incomplete extension. For instance, it only works when you search on Google by typing your query into the Omnibox of the Chrome. If you open google.com and then search, using Google Instant, the extension does not work yet.
