Whether it’s starting a new medication or a new dose, changing jobs, or ending a relationship, Significant Events are arguably one of the factors most important to analyze and gain insights from, and rarely does a significant event only affect mood and nothing else. There are several good ideas buried in the comments of another suggestion about this feature, and I think Experiments provides a good existing framework for building this out to be more useful for users without it being an entirely new feature or needing to fit every possible use case.

One possible limitation of Experiments is that it doesn’t count days/completions that occurred before the experiment was set up, so if this suggestion is adopted, I think it’d be best to enable retroactive experimental analysis.
