Now it is in Python version. So it's doesn't care which version of Maya you are using (newer than 8.5). But the cost is performance speed. C++ API plugin will work more fast than Python API plugin, so if you want more fast version, please contact me.
OK, That's it, hope you enjoy it. 
If there's any bug, crash, something could be optimized. Or you what the plug-in run on other version of Maya. Just email me to :  adamastwl@gmail.com
