This suggestion isnt reallly an addition so following the format would be weird.
So this is what my suggestion is. Personal safes need to be tougher. What do i mean? well 1 TNT and everything in the safe is gone, 
along with the safe. (that was from about 4 blocks away) one shot with a mining laser 
and Bam! Half your stuff is in the posstion of a thief. 
The other half? it magically disapears.
Personal safes need to be stronger. Because at there current state, they arent helping enough. I really hope you add this, i have lost so much stuff because of this.
