Customise the new tab
This is a Chrome extension that replaces the New Page tab.
It adds a toolbar icon that allows you to add any page as a "bookmark" (not a browser bookmark).
These bookmarks will appear in the new tab page, and can be modified and positioned by dragging and dropping. The bookmarks and their location are being stored in Chrome's storage so they should sync with your account.
Additionally, you can add bookmarks manually, providing a title and URL through the new tab page, by clicking the + button.
To edit or delete a bookmark, click the pencil icon to go in edit mode and select the bookmark you wish to modify.
