I'm sure this has been mentioned a bunch already recently
Stock bin
Holds 500x stockpilable item or 25x large item(log/boulder)
Immovable
2x2 tile footprint
Requires wood planks, rope, and metal nugget(nails) to make
Bonus: linkable to merch tables, display average quality of contents on inspection(I imagine this is near impossible to implement though), variable material/label text can be assigned, ability to craft from stockbin (like a barrel)
Need high q logs that your tree guy has been growing? Check the general-use-high-quality stockbin, so you don't accidentally take the log that has been laying around for days that they were reserving for something more important!!!!
Need to store a bunch of bones that you might need in a month's time instead of taking up valuable floor/cupboard space and feeling the need to make a huge footprint village to account for it all? Make a stockbin!
P. S. A visual indicator of whether or not a cistern or silo contain something would be nice
P. P. S Please address steel refueling, the Salem method was way more forgiving.
