Per some feedback by @udonbaka I present to you " WaniKani Vocab Single Character Grid"
A quick and dirty script to make the vocab page look more like the radical/kanji pages.

Any chance this can be modified to also work on level pages? Thanks! (I know nothing about scripts so if that would be a lot of work, then no worries.)
This was something I was actually interested in! Thanks for taking the time to make this!! 
I wonder why it wasn’t made this way in the first place, though.
Updated. Simple change.
Wonderful. Thank you very much!
It’s been helpful. I like this! Thanks! I wanted to add this script to The New and Improved List of API and Third Party Apps but I’m not sure in which category so I didn’t add it. I wonder if we could have this script running on kanji page? Like this one in Found in Vocabulary.
