Introducing WaniKani Stats (beta).
Adds a “Stats” button to main menu, which replaces the dashboard with some stats. Clicking that button again, brings back the normal dashboard.

Fixed Level Progression Tab
Thank you so much for creating this!
I’ve just installed the script and added my API key, however I seem to be getting your stats:
Just thought I’d let you know in case it was a bug. Or, it could just be me! That does tend to happen …
Whoops, looks like I left my read only key hard coded in there from early testing.
For whatever reason when I take that out, the whole main area fails to load. I’ll have to look into this more in a bit.
Just updated to version 0.3
Still needs some visual tweaking and performance enhancements, but it should at least work correctly now. 
I just tried updating but unfortunately I’ve still run into the same issue. I tried updating, uninstalling completely, reinstalling, turning the script off and on again, etc.
I had a quick look at the code and it looks like your API key may still be in there (line 11289). After I hardcoded my own API key into the script, saved and refreshed, my stats appeared! So hopefully an easy fix for you. My backend skills are rusty af and it’s late so I may attempt a proper fix tomorrow if you don’t get a chance to look at it.
Dagnabit, I did it again. When page wasn’t loading, I put my key back in, to see if pulling key from the store was somehow related, and never switched it back.
Just pushed v0.4
Hahaha it’s all good, v0.4 is working perfectly!
Thank you again for writing this script and for patching the bug 
Rewrote this script. Now using WaniKani Open Framework, meaning no more manual API key entry. Also added an Item Details section. More stuff to come as well, as I have time.
Is there a way to filter levelProgressions? I reset in the past and want to only see my current run.
Thank you!
Sorry, been a busy few weeks. Just pushed an update which should exclude any level which has been “abandoned”, as WaniKani refers to them. I haven’t ever reset myself, so I’m not really able to test it out.
Hi, nice script, thank you very much. Almost everything works for me, but I have an empty “Items at Level” graph, and my “Item details” tab only goes to level 8 when I am level 12. Any help?
Well the level 8 is embarrassing. Seems I must have set it to 8 for testing (to speed up the loading while I went to it over and over), and never set it back to whatever the users level is. That is fixed now (though I have a small styling issue to fix, the items overflow the grids)
As for the Items At Level, I’m not sure. I’ll have to dig into it more when I get time. My first guess is it has something to do with the fact I have every item unlocked? something about locked items must be messing the graph up?
Or, I do have items at every level… Could be if a level doesn’t have any items, that’s messing it up?
I should also update the title to Items At SRS Level. I’m confusing myself here now with level vs srs level
Hi there! No worries but… I installed your script, but, even if the WaniKani Stats extension is checked green in tampermonkey top bar dropdown, the only visible effect is top boxes are larger and element disposition is slightly different. No additional Stats menu. お世話になります！
If you’re at the dashboard, and hit F5, does it come back when the page refreshes? I’ve been fighting with WaniKani’s turbo events on this, and a couple other, scripts. It seems some elements, including the stats button, don’t come back after navigating away from, then back to, the dashboard. Thought I had it figured out, but just tested moving around the site, and yep, it disappeared on me. F5 brought it back though. I’ll have to keep fighting that damn Turbo. I hate that thing.
