Changelog

Added

• Multiple datasets, one project — bring in a second spreadsheet, create new datasets from your analysis, and ask questions across all of them at once.
• Anna remembers — your preferences, your terminology, your context. Anna carries it forward so you don't repeat yourself.
• Referral rewards — share heyanna with someone. Earn rewards when they sign up. Manage it in Settings.
