I agree, lats amount is always used as starting balance of the next journal.
And for the next date I always search for the last statement date to be able to know from which date I need to import the bank statements.
I think this is also interseting for bussines owners, as most of the time they will like to know which is the balance of its bank accounts (which are represented by statements). So I think this also makes sense for statment.
This action can be used latter when the dashboard is included in base.
