In the spending plan, categories are assigned a planned value, which remains the same for every month. It would be great if you could let the planned value for selected categories increase by the amount which was not spent in the previous month.
For example, for the Eating Out category, if the planned amount is set at R500, and I only spend R400 in this category this month, I would like the next month to have a planned amount of R600, as I have saved R100 this month.
Of course, the user should decide which categories should have this "roll-over" feature. Also, the planned amount should revert back to the original value (R500 for the example) when the allocated amount has been spent.
