Tamtam messenger is a good chat application,but lacking the sign to identify a send messages from the once not sent and the once not read yet, and this sometimes do not allow users to know if their message is delivered or not.
I will suggest the notification sign should be added to tamtam chat application, so that users will be able to know send, delivered and read messages from the once not sent and delivered.
How it is currently
Example with a delivered messages
Example of a message that that has not been delivered
Where it can be placed
It will eable sender saw that his/her message has been delivered.
It will increase the number of users and increase the popularity of the chat application.
