I will not be hold responsible for any damage or inconvenience this addon might cause for any reason.
This said, I have tested this addon on my main account for quite some time and try to do everything I can to make your experience with this addon as good and as safe as possible.
I admit, this is not an addon for everyone. There is no interface defining the rules for you by clicking buttons, you have to insert them by text.
A wrongly defined (but valid) rule may cause severe damage when fencing, destroying or deconstructing as the items will never return after such an action was taken.
