New Tab Metro is a Chrome add-on developed by Daniel Grimm. It falls under the category of Browsers and specifically the subcategory of Add-ons & Tools. This add-on provides users with a metro styled new tab page that displays their bookmark bar.

The main feature of New Tab Metro is its ability to easily add new tiles to the new tab page. Users can simply create a new bookmark using Chrome's bookmark button, and it will automatically appear as a tile on the new tab page. This makes it convenient for users to access their favorite websites quickly.

Additionally, New Tab Metro offers a sidebar that can be opened with a right-click. From the sidebar, users can open recently closed tabs, allowing them to easily retrieve any accidentally closed tabs. The new tab page can also be personalized, giving users the ability to customize their browsing experience.

Furthermore, New Tab Metro allows for easy editing of bookmarks and folders through a right-click menu. This makes it simple for users to manage and organize their bookmarks directly from the new tab page.

Overall, New Tab Metro is a useful Chrome add-on for those who prefer a metro styled new tab page and want quick access to their bookmarked websites.
