I'd love to have the ability to designate items for trade from the Loo(k) menu, ideally persistently designated items that are automatically flagged to be traded any time goods can be moved to the depot.
Being able to search through the move goods to trade dialogue with wildcards would also be excellent.
...and if that's doable, perhaps just an tiny little switch on workshops that designate all products to be auto-trade flagged?
I do like the idea of being able to put stuff in the depot automatically too.
