I've been thinking that one thing that would increase trade is 'inventory containers' of a sort. For linen and silk, this would a dowel rod on which linen could be rolled onto I would think it should be 4 spaces tall, and could contain up to 300 pieces. After it gathers 50 pieces, it becomse 2x3 with a new sprite obvious, and 3x3 at 150-250. It would take a stick or two maybe a block or two to craft. The rollover display would Show, Item name, Quality Level (which could be the dowl rod [useless unless capacity is relevant], or the average quality of the linen (although individual linen should retain quality) , and Current # of linen contained.
You could, alternatively code it off of the build UI. Where the rod shows current content/Max capacity instead of the three usually used for building. Just remove the last # and the build button. I mean...we already use it for 'quantum storage' anyway.
It occurs to me that troughs might also have a more intuitive functionality through this display.
IF you have a build display open and you shift click the bolt of cloth or the 'quantum storage' window and then it would transfer the items from the bolt to the banner...or whatever you're building.
Of course you might want to fix the method by which window focus is determined. Currently it's a little buggy.
The primary purpose behind this would be to make trading, storing (and stealing!) large quantities of these items more viable. As the map increases and bulk transportation is added and instant travel is removed or reduced This would be a powerful game mechanic. Obviously the actual size and capacity are just suggestions and a better more balanced figure might be applied if this not such.
There are likely other things which could benefit from Quantum Storage. Log piles, lumber piles (for boards). Which would not be in the inventory but a built object that you could store hundreds of beams of lumber into. We already do this and I think Gautemus suggested woodpiles already for this reason some time ago.
