I have a question about this plugin

This is the place for your questions. You have to actually ask it though.

As for the tornadoes in it, is there a setting or option to edit what it does? Like pickup specific blocks etc?

You can blacklist blocks or if you create a custom disaster and spawn a tornado you can modify what blocks it will be made of.
