When shall we expect an increase in the number of different items in the trade hub of Dodixie?

you can shift click your active ships to always have a dedicated window in your station with the filters avail ; same you can shift click your item hangar in compact and list mode to only have the cans visible in a list so you can move them quickly from your active ship filtered items.

IMO a bigger issue is that you can’t sell from cans.
I reported this bug IG and made a post here since I can’t see my reported bugs

I think cans are a better solution because they reduce the amount of items you have (need to stack them) and therefore imrpove the DB performances.
However with mutaplasmids they went backwards, as it implies a lot of creation of different non stackable items.
