in v2 I found this report really useful.
It only showed incomes that had been settled i.e cash amounts, credit card amounts and totals.
This report was easy on the eye and only showed what I needed to see.
I would be really happy to see this added @emre
even in v4 you can keep track of payments made!
but if you want to manage the cash you need to work with accounts
Payment types and income, expense transactions was hardcoded in V2. Now it is dynamic so we need to create something customizable. It is in my todo list.
