Bookmark Express is a free Chrome extension that lets you search and show your bookmarks in the Omnibar, just like other Chrome extensions, but you can also get more information about each one, including the full name, and location in the filesystem, and the URL.

Download the extension, go to the Options page and select Instant Search to start using it, just like the other extensions.

If you want to search your bookmarks, then install Bookmark Express.

You can add a bookmark from the Bookmarks List by clicking the Add button. You can also bookmark a site from a URL by using the Bookmark button.

After a search, the results are sorted by popularity, so you can quickly find the most visited sites and even see if they've changed. You can even sort by tags and categories.

Bookmark Express doesn't show the new URLs you add so it won't be showing you any new pages. If you want to see the new pages, then click on the Bookmarks button.

You can now search and find your bookmarks without leaving Chrome.
