I personally miss seeing the number of connected friends and the total size of the available shared files in the advanced connection window. It's kind of pointless to observe that a node is running at 99% efficiency if it is (hypothetically) only sharing three megabytes worth of stuff.

I did not see an option that toggles between the old format and the new bandwidth/efficiency format so I presume this is a design change.

Does "bandwidth" in this case refer to how much stuff the node is sending me, or it's total capacity? I'd hate to think that all of the normal and child nodes I've found so far are simply dial-up connections.
