Given that you want to build one early but then you want to move it away from your central hearth as it has zero actual "functions" and is basically an oversized decoration, it's irritating to do the microing of knocking down it down in year ~2 just to rebuild it further away. Just let us move it for free, like the Scarlet Orchard's Archeologist's Office.
Having an upgrade to the Main Warehouse to be a "Trade Hub" with both functionality would be really smart and cool!
I think the trade hub should just not be a building. Integrating it as an upgrade to the storage could be an option.
Yes move option would be nice.
FYI: Archeologist office is moveable BUT cost resource to move
Yeah, it feels kinda weird to just put it in a random corner, because you really just want it out of the way and don't need it to be connected to anything.
Another option would be to build in the trading post functionality as a warehouse upgrade.
Yeah it seems to be a bit of a holdover from previous trade mechanics. It still has the red arrow indicating the entrance even though nothing has to be delivered to it anymore.
Honestly, at this point I'm not even sure it should even be a building. All it does is open the trader window and display the icon when a trader is there (which sometimes interferes with other UI and makes me open the window when I'm trying to assign workers or something).
