This was my first project that got more than 100 visits
Congratulations!
I downloaded the WK levels and the frequency.
One thing you may or may not want to add, for people like me that have to complete a collection, is just doing a single ZIP file for the entire WK, grade, JLPT, etc lists on top of offering the singles.
Entirely up to you though and since I got what I needed… Yes, it’s all about me (I am kidding).
I just need you to do the JLPT N1 to complete that set
Not that I am anywhere close to there in Kanji knowledge…
For those looking for a paper like feel on digital, I actually find the writing surface and the pen tips on the Surface line to feel pretty close to paper. The iPad Pro also gets close to real paper feel as well. Close is not the same and not perfect though.
And of course, no one HAS to move that way but if you don’t want to waste paper, etc it’s an option. 
EDIT- bought you a sushi. The site kept saying buy a coffee… I kept thinking… coffee sushi? Ewe…
