I was actually a bit surprised that I did not see this simple flag requested here somewhere already. My servers incorperate a jail system for various offenses, and sometimes a player will be sitting in there for quite some time, depending on the severety of their actions. A common issue reoccurs where a player will either refuse to eat (lol) or is already starving/dehydrated when they were jailed. This results in some funny situations but it can also be a nuisance. I thought it would be quite useful overall if there were a way in which they would always maintain the max default values for metabolism while within the 'jail' zone (250 hydration, 500 energy).
If at all possible, please consider this small idea for a future rendition of the plugin. I would be most grateful, and I know others would find it useful as well.
