If this gets a toggle to turn on off like flux mining, this has my vote. Especially if it's say limited to your town plot, or your wild chunk .. and maybe only works if YOU do it - so if i have build perms in tidal's plots, and i try to use it: wont work. That way i know i am the only one damaging my stuff, and not someone who abuses their tnt blast perms.
but yeah, id love to have some vanilla stuff back!
