I haven't made a video or written up new documentation on it yet. Basically turn it Rollover budgets ON for the budget categories that you want to be rollover budgets. Then the unused budget from the last month will continue to carry over to the next month. If you want to reset the rollover then you enable the Variable Budgets and there will be checkbox that allows to you restart the rollover budget in a certain month. You do need to turn on Variable Budgets and set when you initial Rollover budget will be starting.
From there on out you will see under the Available column:
March $50
April $100
May $150
...
adjust of course for any transactions for the period you are looking at.
