I am working on a seminary project and realized something that would be very helpful but can't find how to do it or if it's possible now. I use the highlighting feature extensively but think a huge addition would be tags. For example, I have a highlighter for any verses I find to be demonstrating the "word of God." Now as I am working on the project I find a number of ways the "word of God" is applied, defined, or used. It would be helpful to be able to assign different, created, tags to each verse to let me organize and categorize them freely as some may apply to more than one designation but all fall within the "word of God" highlighter.
Is there already a way to do this that I am missing?
