How to make gnucash track something other that national currencies and securities, for example, DVD-RW Discs, books and other things I can lend to people. I want to know who owes me some discs and where should I return lent ones. They also can have "exchange rate" and can behave like a currency.
I tried to simulate them by creating a security named "DVDRW", but it adds more strange fields like "shares" or "price" I don't know to do with. And I can't just add a fake national currency named "DVDRW".
How is it better to track non-money with gnucash
