One thing that is bothering me is when you changed the view of what was going on to not include the individual file displays. Now, if there is a large directory that is being worked on, it can appear that the program is stopped or stuck. Is there any way that you could include some sort of indicator that the program is still running?
The display should update once per second. You're right, it does seem from moment to moment that perhaps nothing is going on.
It does need to be better -- one guy opened a ticket because he thought the new Replicator was skipping files.
