For the Smart Tipping feature, flat tipping "below" a specific threshold is available in "Tip Suggestions". It would be nice to add flat tipping "above" a specific threshold as well. Some customers spend $200 to $300 and leave a $5 tip. The merchant can post a minimum tip amount on transactions over a specific dollar amount on the menu so the customer is aware. This would be a great feature to protect the waiters and waitresses.
