Sadly I just didn't use it much, most new tabs I open from my bookmarks bar, so I scarcely ever saw it.
What might be useful is having an option to feed the bookmarks bar into the new tab page so they're the same?
Also - making it mandatory to put a picture for every page you add was a bit much, can't it use the image from the web page itself by default? This was a very frustrating feature for me, and a pointless extra step when I'm working and just want to get things done.
