♥ love it ♥ Rated 5 out of 5 stars

I love the feature "find style for this site" then choose: Global Dark (better for your eyes and your screen).

♦ One question:
How do I write an Exclusion within a rule: In plain English: apply style to all "div *" except the one with "div.contentBlock *" .

Something like ( "&!" means "AND NOT"):

div * (&! div.contentBlock *) { background-color:black !important; }

Would be almost perfect if add-on has: Shortcut key to turn on/off.

This review is for a previous version of the add-on (1.2.6). 

div:not(.contentBlock) { background-color:black !important; }
