Update about 1.13 support: I've finished coding the new version, now I'm going to test it and fix bugs. I should be able to publish a Beta version soon. Meanwhile, you can visit my 1.13 testserver (prunt.nuhvel.eu), where you can play around with the plugin and report bugs (please make sure to clearly state that the bug was in the new RC v2.0, not 1.x).
