Parts of what you'd like to see are available, but I agree it would be nice to see a clear summary on, say, part of the monitor page

The total bandwidth, subdivided into gnutella and files (http) is available for both upsteam and downstream in the Tools->Satatistics->Bandwidth graphs.

The files total wouldn't make much sense, since many requests only ask for part of a file. Thoses stats are available on the Library for each file, but there is no total. Still, even a total at the top of each header column would be interesting.

I like the idea of a ranking, something like a bitorrent ratio. It would be nice too if these stats could persisit over many sessions.
