Thank you for this thread, it’s great. 
A few notes though:
- it’s impossible to edit the scripts on android (firefox) either before or after installing them
- it’s impossible to uninstall scripts - you’ve gotta uninstall violentmonkey entirely and then reinstall the scripts that do work.
A couple of scripts that work on android:
- WK Anti-burnout
- WaniKani Lesson Filter
- Lesson/Review Count in Forums (hides some of the top of the page though)
Doesn’t work last I tried:
- WaniKani Pitch Info (might work now that the code’s changed)
