Delete messages even on receiver user
Currently, if the user delete a message in a chat with another user, the message is deleted only on the local phone.
It will be good to have the possibility to even delete the message (by requesting if the user wants to delete even on the remote phone), or all the messages, even on the remote phone.
I know that now there is the "Disappearing messages" feature, but it isn't the same (and the 7 days only option isn't enough)
