The trade order form supports to select towns by their name, or by player name, listing matches sorted by distance. Sadly this doesn't work for faction hubs, neither the hub name, nor the faction name.
Of course I can bookmark relevant "send to" pages, and then erroneously click Send to Grovinton instead of Send to Mataba, resulting in a days long trip instead of one hour. I can also pick player town Matombo Haven when I actually want faction hub Matombo, and adjust the coordinates with a mini-map navigation.
It would be much better when I can type Mataba, and get Mataba, without using the map: Loading the map over reduced bandwidth can take minutes.
BTW, should some faction hubs really offer "harvest" on the map? So far this always resulted in disappointed caravans for me.
