Pros
Pro ToDo list
ToDo list is one of the most important things which is supposed to present on every new tab. Sync ToDo and Calendar make it very comfortable to use.
Pro Super fast
The add-on contains only the needed functionality - time, temperature, todo and that is all.
Pro High-quality wallpapers
Pro Free and Open source and gets the job done
FOSS and has necessary features to make a great start up page. Highly recommend.
Pro Has a web version
Phones usually don't support extensions. A web version is a godsend, especially since it has a dedicated mobile webpage.
Cons
Con Language support
For now, only English language is available.
Con Essential features only
This extension features a few but useful features only. But it is a great new tab page nonetheless.
P.S. If you wanna add new features, you can just fork the source code if you are that kinda guy (its FOSS).
Con Limited customization
Widgets can't be customized a lot.
