So far I've tried 4 different configurations:
Momentum. Great for keeping track of to-dos and get inspiring quotes. Packed nicely with some beautiful images.
Daily.dev. Lots of tech news and post from various sources (configurable). I became too distracted from my daily tasks.
Devo. My current New tab set-up. I like how it displays trending news and hot projects/apps both at the same view.
How is your browser's New tab configured?
