can not edit message after sending
I use the Jami gnome software. After a message is send, if I see an error in it, I can only delete it for rewrite it edited. An interesting feature would be have a "edit" button with the "delete" button when I click on the "..." next to the message. Next, the message appear in the text area on bottom, when modifications are finished, type "Enter" and the modification is send to the chat-friend.
A screenshot of the "delete" button (french interface):
