Feature description

As far as I understand the app, the last message sent in a conversation is indicated by a tick to show whether the SMS was sent correctly and received correctly by the recipient.

The determined status of older SMS messages is not retained. A later check by the user is therefore not possible.

Solution: Save the status permanently for each message sent.

Why do you want this feature?

Increasing user-friendliness and transparency

When a message is selected by long pressing, it is possible to go to the Properties from the menu. In the Message details there is a time of sending, but unfortunately the time of receiving is missing.
It would be great if the Message details included the message status or in case the SMS was sent correctly and received correctly by the recipient not only the time of sending but also the time of receiving.
