Since Cashy-POS 1.9, this screen now displays two different views. You can toggle between the two views by taping into the log screen

• SubTotal view
  While registering, it displays the permanently updated subtotal of the running transaction. Once the transaction is closed by one of the payment methods, it will display the end parameters of that transaction. Means: payment method, received/returned change, etc
  The subtotal view will only display something if at least one item is added to the transaction-screen (top left)
• Log-View
  In this screen you can see all transactions and events since the last «Close-Day»-event in »Z»-mode.
  You can scroll through all transactions and if tapping longer, you can choose to send all transactions to the receipt-printer. After a «close day» in Z-mode the Log-Screen will not contain any data.
