I am looking for a fast/easy way to add and/or remove sites from a stylesheet. Probably something like an added context menu option in the browser with a plugin. 'add site to ___ style' etc...
Example: I love dark themes. I have a global dark style but using it is a pain because some sites have their own dark themes, some have great custom stylesheets from Userstyles.org and some sites just break when using some global stylesheets.
I say add or remove because this would enable multiple options like:
-leaving a global stylesheet enabled 24/7 and easily remove sites from it as needed
-converting a global style to only work on specified sites which can be quickly added with the click of a couple buttons.
