I made a module so I could track the verses that I have highlighted. I use each color for a specific topic, like green for promises, blue for verses about Jesus and red for warnings, etc. I made a 'contents' page with the colors and what they stand for and an entry for each color. Whenever I come across a verse or passage that was highlighted before I started the module, I copy it to it's entry in my Highlights module, otherwise, I copy it to the module when I highlight it. I like being able to read the highlighted verses by their colors/topics.
