this saves my eyes on the daily basis, thank you so much

This is nearly 100% perfect. However adding 2 extra features would make it phenomenal!

-An option to whitelist a link or website.
-An option to change the toggling shortcut.

Exactly what I was looking for. Very useful when I watch online training where often the background is white, which is very blinding on my Linux desktop environment which is set to a dark theme. Thank you very much for this extension which saves my eyes and my stress.
