By the way, did you notice the tooltip which appears when you hover over that checkbox?
Do you think we need to make the tooltip more descriptive? Does it need an extra sentence or something?
The tooltip currently says:
If checked, ratios between precursors will be calculated as the ratio of the sum of transition areas.
Transitions from the two precursors will not be paired with each other for the purpose of handling missing peaks or calculating ratio dot products.
