There have been several times now where I have wished I could choose if a particular item could be eaten by a player or not.
For example, turning a normally inedible item such as a shoe into an edible shoe. Why? Because it would be funny and it would open up a lot of opportunities for creating hilarious scenarios.
It would also be good to turn off the edibility of a normal food item in some scenarios. Especially if it is a quest item and you can't afford the player accidentally eating it and not being able to get another, essentially breaking the scenario and preventing progress. The Indestructible option is a good start but it doesn't prevent you from eating it and destroying it that way.
