SUGGESTION

I know there is a flag to prevent tnt, creeper ect.. from exploding while in a protection field.
What I would really like to see is a flag that would allow the explosion, hurt the player but not damage any blocks, similar to what Essentials has when you disable creeper block damage or wither block damage. Maybe this flag could encompass all explosion block damage, tnt, creeper, wither ect.. or preferably a flag for each perhaps with a parent.

prevent-explosionblockdamage
is parent of...
v
prevent-creeperblockdamage
prevent-tntblockdamage
prevent-witherblockdamage

Something like that.. Thanks for reading. I hope you take this into consideration.
