thank u sm developerr!! such a great extensionn. A MUST HAVE AND TRY

So far so good and does what it was supposed to.

The fact that it doesn't require any permissions is very nice. For only the sake of having a background image for my new tab page, I installed various extensions and they all needed loads of arbitrary permissions.

The luminosity feature is a bit confusing, but aside from that it's a very good extension.
