When a new update is created and replied to the first time - it is somewhat easy to see what it is for.
But it starts to get messy fast as the replies continues on the same update. When clicking on reply on another reply it would be nice if its not just an @ that is added - but that the reply is nested below the reply that you actually are replying to. Now they just get added below eachother, so it is hard to know which reply is replied to.
Messy to explain 
Instead of this:
- Update
- Reply to update
- Another reply
- Reply to “reply to update” but its not apparent
It would be:
- Update
- Reply to update
---- Reply to “reply to update” where it is nested under the reply you actually replied to - Another reply
