Here's the deal: I created a custom form with some new fields and published the form to a public folder. I then opened that form in design mode as a different user, made some edits including adding some more new fields, then published the form to a different public folder. Now my newest custom fields show up under "User-defined fields in folder" and the previously created custom fields show up in "User-defined fields in this item" when I look at the all fields tab.
Is this something that I need to worry about (folder vs. item)? Why the difference? Is there a prefered method?
