Spoiler: Small feature that everyone likes

the "dark theme" to read a chapter... only 2 icons have to be made for one be inside the popup panel in the "Reading Options" with a JS trigger to change the css background color for ("page","main read chapter"."wi_news_body") to #000 (or preferably a gray one like #222222) and changing all of the text to #ffff (or preferably a gray one like #bbbbbb) for the "wi_news_body" and changing the icon for the other one; through it will be great if the setting can be saved for reading multiple chapters you don't need to click the icon every chapter
