We have the ability to hide item type properties by manually specifying it. However, I think it would be useful if we could hide a property based on a pick list value or another item type property value.

For example, if I have an item type that I would like to use a pick list to specify if I want to calculate a quantity based on either a volumetric measurement or an area measurement with a user-entered depth. If I use a pick list to specify Area, then I'd like a property for the user-entered depth to be displayed. But if the pick list specified volumetric, then I do not want the user-entered depth displayed, since this won't be used in the calculation.
