Thanks. I had missed that (or seen it but misunderstood it).
As far as the ergonomy is concerned you are probably right, it is not a change
one makes often, but I guess making this more obvious with some hint or link in
the statistics screen would help.
Also, aMule could perhaps try to auto-detect or
guess the real line capacities from the actual traffic taking place.
Also, it is counterintuitive to have these settings not grouped with the
"Connections Graph Scale" (Preferences > Statistics). If they need to stay
under Preferences > Connections, then why not duplicate them?
