Group MMS is critical for basic MMS support in Chatty. What is needed to close the issue (there may be more? But testing is needed):
- Be able to add multiple contacts and create a new Group MMS. See #235
- The "Chat Details" page of a Group MMS does not show the members of the chat.
- When received, the "Title" of the Group MMS is just a comma seperated list of the phone numbers in the chat, and has no concept of contacts. There needs to be a way to change the title to reflect contact details.
- If Chatty is closed and reopened, a Group MMS can show up twice. This may be an error in !768 (merged) , but I am not sure.
