I pressed the button next to exchange rate to see what it does, the button doesnt have any hints saying what it does and when pressed nothing happens. so I entered a wrong receipt because of it. now I have to check every other action i did this few days to see what is flipped and what is not, in case I accidentally clicked it on one of them.
It should indicate somehow that it’s using the flipped version of the exchange rate.
One idea might be instead of (1 = [ ]) it should turn into (1=1/ [ ])
that was my problem, I left the CODE empty when defining the currencies.
