Just mention about it, your preview screenshot should place the picture "before" before "after", else it's really confusing at firstly look.

P.S. Option "Dark Mode" doesn't work well with extension Midnight Lizard enabled, file icons all turn white.

P.S. And the extension name is a bit of too long, that it blows up right-click context menu. It would be better if you could make it be configured somewhere else.
