Floreant POS software customization

I want to make some customizations for the floreant pos. 1. There are two receips that print in floreant. Ticket and kitchen receipe. I want to print a third receipe called "order number" only with the order number, not more text. 2. I want to show a user a popup message asking if he want to print the kitchen receipe or not. 3. I have the inventory plugin and I want to generate an inventory report with this information.
