Just a heads up, the dash is most likely going to break on the 6th.
Due to the proposed modular nature I can’t very well gauge when a patch might be ready, so in the meantime you might want to restrict the style to non-dash pages
How would you that you ask? Simple:
Open the style and change the field at the very top that says URLs on the domain to URLs matching the regexp and paste the following string next to it (including the quotation marks)
"https?://www\\.wanikani\\.com/.+"
It should end up looking like this:
