I have really noticed this more since the category inspector was released. When a category has transactions for the month but they all add up to zero the outflow box is empty instead of zero. I think it would be better in these instances to actually display zero so you know the category has had transactions and you can click on them to see the inspector.
My reimbursable expenses category suffers from this the most.
I agree.
This totally makes sense. It also will totally not be trivial to implement... Hahaha... yay.
