It makes a lot of sense to take the recuring bills and income and add them automatically to the budgeting periods that they occur in. This way all income and recurring bills are already accounted for each period.

This way all a user has to do is fill in their envelopes for the period. It makes no sense to have a user enter the data manually for each budget period when the data is right there.

You can even make this a toggle in settings "Show recurring bills and income in budget periods" so if people like the old way they can just leave this feature off. This option would just add a new expandable table row to the Inflow and Outflow that would have this recurring data in it. the data would not be editable, if you want to edit it then go to the recurring data section and change it there
