Is there a timeline expected as to when this will be out of Beta? Can there be more fucntionality added, please??

1. a little "thank you, please remove your card" message after a transaction would be great. Customers are always standing there staring at me after the transaction is finished.

2. please move the grand total to the BOTTOM of the screen, customers get confused and argue with us about the total because they dont notice the grand total at the top of the screen, and i would suggest changing the color of the grand total to something that stands out more, red possibly even though it may not match with the color scheme, it would be more useful.

3. signature input on the customer facing display.

these are 3 very important features. can these be addressed, please??
