Quoting twoelk, I will also like this feature
does/could this have a command to list all my areas with coordinates? Could be helpfull to find lost or >forgotton property or just to get an overview of all my clained blocks. Could be even more usefull if such a >list could be dumped at the client side, that is local to the player.
SmallJoker already implemented this in his fork "simple_protection"
Basically, with "/area list [name]" it will give you list of coordinates of your claims, and if you have special privs - you can get lists of claims of other people.
