At first I wasn't fond of the layout for this script, but after I drafted a field effect I wanted, I get why this script was created the way it way. It gives a blank slate to create unique field types, like an underwater situation!
I'll try to maybe change the layout of it eventually. I'm not a good enough coder to make it more 'plugin' sadly.. Thank you :) glad you seem to have discovered the best way to use it!
