# 🧮 Formulas Improvements - Previews

We've made a few changes to simplify formula creation and troubleshooting:

- Preview your formula with a recent run to validate the calculation
- Keep track of parentheses with color-coded parenthesis pairs
- Add a note to maintain context of any assumptions in the calculation
- Add your own custom constants
