Stats recorder, with a few other features.. such as if you get 'stuck' in town , it will attempt to get you unstuck.
Also, my personal favorite feature is that you can set the client sizes to 5% and then hide them. This greatly reduces lag that having multiple SRO clients usually gives you.
My CPU usage with 3 clients all 100% size is around 65%, with them all 5% and hidden my CPU usage is only 12%
