Adds a 'Show All Spoilers' toggle button. Setting is saved per thread.
In certain threads (Game of Thrones) where a lot of text is rightly and politely behind spoiler tags, it's a bit tedious for people that don't care about spoilers to click the 'show spoiler' button on every single post.
This script adds a small spoiler button in the upper right to every thread header section, next to the 'bookmark thread' button that will, per thread, open or close all spoilers. This preference is saved until you clear your cache.
Feedback and/or suggestions welcome.
