I feel as though this feature could even involve a certain level of crowd sourcing for fixes on specific websites, potentially with community voting for moderation and implementation. Also, a right click menu option to quickly add/remove a website to/from the disabled list would be great, as I hate having to disable it for all websites (especially if I'm flipping between tabs) and it takes too long to get to the disable list to be worth the trouble.

@Pyll0 Thank you for the reply. However, running the chromium flag has miraculously turned all websites dark (i.e. white text on black) and with Opera's own dark mode that is all I need.
