I see that it's a required field, but I was able to remove the requirement and the field with Studio. My objection is that it's a unique user-input numerical field. Shouldn't this be an auto-incrementing value?

I've read everything I can find in the developer guides. Does anyone know if I can safely do away with it or at least make a change so I don't have to think of a unique number each time I make a new project task? Thanks!
