What I like: I can set my very own, very simple filter, and that is all I have ever wanted a dark mode extension to do so as to replace my having to apply the style change myself to pages that I want not so bright.

What I don't like and makes this extension a no-go for me: The developer makes getting to the extension's preferences way harder than it needs to be (I have to access it from the AOM page after getting to it in one way or another every time I want to update a setting for this extension - why? At least give us a right-click to a pop-up or the options page...); and, the exclude functionality does not work with domain names alone - subdomains must be added separately, the label for the exclude list field does not mention this, and it is really annoying on large sites or sites that offer multiple services through various subdomains (at least there is a context menu item to disable the extension on a page but only after it has already executed on the page).
