How do columns work?

Ok I get that there is automatic and manual, but I put in automatic and there seems to be no rhyme or reason to the pattern generated.
And on manual I have no idea how I'm supposed to make it work, there seems to be no documentation to explain it, and the tool tips aren't useful at all.

Please explain how I make it work with manual or by what criteria it sorts them via automatic.

Hi again Kevin.

We are working on the automatic option. Currently, what it does, is that it separates the fields to columns of n fields, where n is the number you write in the Field Column Count option. However, this is not the functionality we want it to be, so this may change in the near future.

The manual option is very simple. The Tooltip says "Comma separated list of Field IDs. Each Field ID will start a new column."
So, if you want to have e.g. 2 columns, you can write the 2 IDs of the fields that start a new column.
Example:
Fields:
1 Explanatory Text with Left Column Header
2 #User Name#
3 #User Email#
4 Subject
5 Explanatory Text with Right Column Header
6 Message

All you have to write to create two columns is 1,5 in the Column Field IDs option.
It's not really complex, is it?
