Remember list position and restore it
One of the testers moved a conversation from a forum discussion (that was supposed to be for more people) to a private conversation, because "forums are hard to read". When asked for more details and he said that you have to scroll down every time to the last message, so you have to real all the thread again and again like in a non-quoted email thread.
He said that it would help immensely, if Briar would remember the last message you had read and show it again when you re-enter the forum.
So this ticket is about remembering the list position and then restoring it when the screen is rotated or the user re-enters the list.
There are several list positions we could restore depending on which list is concerned:
- just the last known scrolling position before the list was left
- the position of the message that was marked as read last
- the position of the message that was marked as read first when the conversation was entered
