Thanks for the plugin.
I managed to remove "Price" and "Details" by editing the actual plugin files (not ideal), but now the drag and drop facility is no longer working. (I didn't require "details" and each package has multiple prices – surely it would make more sense not to include these by default as it's impossible to guess what everyone will be using the plugin for?)
<li> only line up with one another when the text takes up one line, once it is over multiple lines the a feature and packages no longer line up.
I also made one package "featured" but them was unable to undo this, so I had to delete the pricing table and start again.
Also how do you rename a feature?
