More inventory suggestions from me... :)
It would be great if tree harvests could be bundled in the same way as grain, with sacks for beans, crates for eggs, and similar things for the other trees (vapor cylinders? bubble bouquets?). 250 per container, and five of those per inventory stack.
It's maybe not as important for garden crops as you don't have to run around as much to collect them, but being able to make 5 by 80 stacks of those as well would make the produce section of the auction house much more useful.
For a bit of game balancing I think the packaging process could have a skill of its own, and maybe require something along the lines of an "all purpose packing peanut" that's consumed when used.
