New Suggestions:
For Item Creation Window: Add in 2 Selection Box Items For "Resource Location" (possibly even a third but only for player's own workshops)
1. Inventory (default selected)
2. Workshop (default not selected)
3. Plot Stores (default not selected)
Count of Resources inside the Creation Window thus can be done directly from the workshop inventory.
Reduces waste of time moving stuff in small lumps from workshop to disk before crafting.
With the third, you could access anything in the whole plot's storage buildings, but only works for that player's own plot.
