Change font, size, width and background of a work + blacklist: hide works that contain certains tags or text, have too many tags/fandoms/relations/chapters/words and other options + fullscreen reading mode + bookmarks: save the position you stopped reading a fic + number of words for each chapter and estimated reading time
This script is essential just for the bookmarks. I don't understand why "bookmark a specific chapter" isn't a standard feature. Bookmarking the specific spot, well that's just gravy. Only problem I forsee is after I've made a bunch of them, will the list get out of hand? A proposed solution: add a button to jump to a work's bookmark in the work's summary in, say, my collections. Then I don't have to worry about the bookmarks menu becoming too full.
