Thank you ^^
Currently taking a small break to get through exams, and then back to durtling.
The heatmap is a function created by the Wanikani Heatmap script, with instructions on how to get it here. But if you have no user scripts before this, youâll have to incorporate Tapermonkey into you browser, with a nice guide here.
For more info on really nice scripts, I recommend visiting chapter 7 of this really complete guide to level 60.
Hope this proves helpful ^^
