The mod is sometimes useful (stat changes for example), but to be completely honest, I very soon started to ignore it and won't use it in the next update.
The reason is that the mod often highlights a choice, suggesting this is the best outcome, although it's merely the author's completely subjective preference. So if you don't know this and follow the walkthrough you will miss a lot of content and maybe content you would have liked a lot more than what the mod suggests.
This mod might do more harm than help you, especially when you play believing this mod will get you the best scenes, so I would advice against using it (or only "listen" to it in obvious situations), and instead to follow your gut on your first playthrough and then try different routes later.
