Field length of OL+ Scalepoints "Fields" field

First, I would like to say thanks for the module. As I learn more about Drupal I am continually amazed at the tools different people have built. OpenLayers & OL+ are no exception.

I am building a multi layered map with Scalepoints in OL+. The challenge I am running into is that the "Fields" field in Scalepoints seems to be limited to 128 characters. I am trying to enter a comma separated list of 4 field names that are a little on the long side and have run out of room. Is there an easy way to change the character limit? If no, I can go back and shorten my field names.

Thanks,

Mike
