The month
- Add an expense or income: monthly, yearly (in a payment month you choose) or one-time
- Planned versus actual: actual starts as the plan and changes when you update it, with a gap column
- Summary cards for income, expenses and balance, with warnings about a negative balance and going over
- Change an item: this month only, from this month on, or in all months, and skip a month
- Move between expense and income, reset "actual = plan", and edit directly in the table
- An owner and a category for each item, with suggestions, and export to CSV
