[Feature Request] Option for Reference/Order-ID/Comment

[DoktorShift]

Add for example an "+ Add" button to the TPOS interface, as shown in the provided image. This button could allow the user to:

• Enter a reference, Order-ID, or personal memo related to the transaction.
• Store this for information example in the additional extra field comment for later reference.

Key points:

• This button should also be displayed within the cart interface when the user is interacting this way, allowing quick access to add notes, references or IDs.
• Helps keep the transaction organized with extra details that might be relevant for later use or organization.
