Great tool, how about ability to have the server load all 4 maps, and switch between them from the client?
Some of us are editing more than one map for a shard.. It may seem petty, but just that little support would be superior to having to shut down the server, and reload it after editing the config file for the alternate map and size.
You can run several instances of the server at the same time. Put them in separate directories or just copy&rename the exe and ini file. You just have to use a different port as well as different map, statics and staidx files ofcourse ;-)
But I guess a command line parameter to specify the ini file couldn't hurt (so you don't have to copy the exe as well).
