DOUBLE THREAD POSTING
Lol, never saw that happen before ^^
In case you haven’t read up on your other thread, I’ll repeat it here:
I made a visual guide on how to install user scripts:
Visual Guide on How To Install A Userscript
Some of the more useful ones are
Wanikani Real Numbers
Wanikani Ultimate Timeline
Wanikani Dashboard Active Topics Panel
Those are only a few useful ones. There are also things like lesson/review reordering etc... WK has a lot of scripts that are fun and/or useful.
A (nearly) exhaustive list can be found here: /t/The-New-And-Improved-List-Of-API-and-Third-Party-Apps/7694/1
Just browse around there and see what you like!
