Describe the bug
In version 0.3.0 one could define a field separator. I had mine set to empty, because I like my forms small and nimble. After upgrading to 0.4.2 there always is a huuuuuge gap between de the fields. Looking at the code the gap is now hardcoded as "\n\n". Which might be fine for most, but not for me.

Expected behavior
I'd like to be able to set the separation between the fields myself, and I'd like to set it to nothing.
