First of all, this is a great plugin. Thank you for that.
However, I've found some bugs:
1. When the plugin auto-claims an area, it is not possible to remove it right away by using the "R"-key. I have to quit to the main menu and reconnect to the server before I can remove the area.
2. When the plugin auto-claims an area, I can not manipulate the adjacent area while I'm still standing in the auto-claimed area. I first have to hide areas. This often happens when I'm attaching a torch to a tunnel wall and then continue digging.
3. The command "/wpp delete all username" does not work for me. My username consist of two words. Maybe the plugin stops parsing the command after the first part of my username.
I'm not running my own server, just playing on public ones that run the plugin, so I can't play around with the plugin configuration.
