Amazing. This one is easy to customize, beautiful, and more importantly (personally) lightweight. And this is open-source too, I give this 5 thumbs up.

The only new tab addon i could find that did what i wanted. perfect.

Easiest to customize, lovely minimal.
Hi, I like that I can color widgets now but I can't get my custom links to look like the other widgets anymore. Custom buttons always have a border and the same opacity can't be achieved with the custom options. I would like to keep the standard grey style as an option, looked really consistent and minimal.

Amazing. All these months I was searching for a dashboard-like extension that could take widgets,notes etc and be beautifully designed like "Momentum". And here it is, ready and open-source too. Thank you!!

Fun extension, I'll be using it in the future! Thanks for sharing it on reddit
