Quick one: Unify the UI for containers between crates and bags/backpacks. Currently, with the UI for “container” open, right-clicking an item in your inventory will place it in a crate, but drop it on the ground for a bag/backpack. You have to drag items (individually) to a bag/backpack. Right-clicking should work uniformly across all “container” UIs.
IMHO. Keep up the good work!
