feat: Timeline sorting
Created by: Amelia
Summary
There's a great feature in Streams to order your timeline by Posted Date, Commented Date, Received Date, or Unthreaded.
Posted Date is what Sharkey defaults to currently, I think. Where a post is received and added to the top of the timeline.
Commented Date will push a post to the top of the timeline if a new comment is received on that post. This is what I'd really like to see implemented. Being able to sort the timeline posts as new comments are received would keep lively conversations up near the top of your timeline, and seems to keep people more involved in their feeds.
