Would be cool if we could pick up placed food by right-clicking with an empty hand.
If multiple stacks of a food item are on a plate, then one at a time would be taken when the plate is right-clicked with an empty hand.

Hi, it is available from v1.1.0 to take items back from plates. You can:
Click while crouching to place all items at once
Click with bare hand to take items
Click while crouching with bare hand to take all items

Ty for adding this! Can now easily grab and eat food from plates while sitting in chairs 👍
