Looks nice but a few things are a bit confusing: 1. I'm not sure what's the difference between -i and -s, they seem to work the same for a few examples I tried 2. It renders every paragraph in a different color, which seems... unnecessary 3. There's a [-] at the beginning of every paragraph which I'm not sure what it is for (seems to suggest that it is to fold the paragraph but I don't really see how to actually fold it).
