Increasing the number of rows for text area for node-body

First of all, thanks for such an awesome module. Modules like this make using drupal a pleasure.

I wanted to mass edit nodes of a type very similar to Page (the use case is almost identical to the one given on the Module home page for editing Pages)

I found the text area for the Body field had only 2 rows. So I looked into the code and made a change around line 149 - namely:

Is there a UI way to achive this? It would be cool to have more config for the module - e.g. the ability to specify the number of new node forms in the view.

Thanks again for such an effective module.
