The option to click an a file that is downloading and seeing what speed you are getting from what host, and then the option to remove the hosts you are getting like 1 KB/s from making room for faster hosts. It's not funny getting 15 KB/s from 10 hosts

Also the option to devide your upload speed between video and others, so that people that are just waiting for a song don't have to wait until someone has finished downloading a 500+ MB videofile before getting to download
