The Notion formula editor received a major overhaul with the introduction of Formulas 2.0, introducing many quality-of-life improvements that make working with formulas much easier than before.
Multiple Lines
No more one-line mega formulas! You can now press cmd/ctrl + enter to move to the next line.
Inline Commenting
Inline comments are now supported! Just surround some text with /* and */ and you're good to go.
Property Tokens
Property references in the editor will as tokens. For example, prop("Number") will be shown as # Number instead.
