I have not yet started developing plugins for RC version because I expect load of changes so I will wait for the final release and they you will have the plugin for version 3.0
Also I have updated the plugin to work with almost every theme and prevented conflicts.
Now there is new admin page in your admin dashboard where you can set if you want plugin to load jQuery for you or you have it loaded already. Also you can point to some external div where you would like to load your full post.
I’m sorry to hear that this plugin doesn’t work for someone because I’ve really spent some time in developing it.
If you want me to help you get it going and to debug it together please send me an email.
Cheers!
