To go along with that-- Support for exporting group messages. I recently moved to a new phone. With the latest versions of signal on android, I had to export a plain text backup of my messages. The problem? All the group messages were removed from their groups and threaded into the individual conversations with the person who sent it. So not only did it ruin the group message, but it also ruined the individual conversations, too.
I ended up downgrading to an older version of signal, creating an android backup of the data and then copying that to my new phone.
