Although I like the new presentation of the touchscreen POS it removed some basic functionality.
* In previous POS you could select the business partner, here it assign the "Standard" partner and it cannot be changed (not sure if there is a "hidden" button to do it).
* The button "Preferences" do nothing.
* Credit Card Expiration cannot be set to 0911 - it's changed to 911 and then complaining about the format.
* The order was completed with an incomplete payment - an order of 200 - I entered a cash payment of 50 and it was completed with a change of -190
