This post has been mostly copied from the Bunpro topic, but I think it would have a lot of value on WaniKani too.
I would like to be able to search WaniKani without having to navigate to the site first. In chrome’s toolbar I can type the first letter of a site I commonly use (e.g. “i” for imdb), hit “tab”, and then I can search the site directly. I believe what would be necessary to get this to work is something in the URL indicating that searching is happening. For example, for imdb, that URL is http://www.imdb.com/find?s=all&q=%s, where %s is the user query that is typed into the search bar.
I think you could use https://www.wanikani.com/dashboard, but by adding a query parameter and using it when navigated to directly, I believe this chrome toolbar search would work as well.
Let me know if anything is unclear. Thanks!
