I really appreciate that you made this. I’ve been trying to achieve something that could transcribe my Kindle Highlights automatically for a long time, and I’ve managed to learn enough Nunjucks to style my highlights based upon color and link each one to the location in the Kindle App. Very cool!
One difficulty I’ve ran into is that I’ve been trying to create a parent Nunjucks HTML template that I can extend styles from in order to limit the amount of code in the add-on itself. However it won’t save with any {% extends "parent.html" %} call. I even attempted to put this in JSON format so that it’s interpreted correctly by data.js, but can’t get it to work. I’d love if the plugin allowed for this type of functionality.
