Visual Speed Dial by Joue

This extension provides visual tabular grids to the new tab page. You can organize your grids for each tab and add new grids. The position of these grids is customizable.

It is possible to have two new group of grids adjacent to the user-defined group: Bookmkars (grids are elements inside a custom folder) and recent sites.

The extension also offers in-page search (with auto-suggestion) using some popular search engines as well.
