Request - show/sort towns in town list by cargo in/out

[nemethv]

At the moment the town view (ie the view that comes up when clicking on a town's name) shows how much mail/pax/cargo is delivered (?) or generated (?) last month. My suggestion is that this feature is somehow transferred into the towns dropdown (the towns list with world pop in the menu) so that we can filter or at least sort by cargo value so as to know if particular towns have not been hooked into the network.
Thanks
