Placing information about what to enter *after* a field seems backwards.
Describing what's needed *before* presenting a field for it makes more sense. I actually think that should be the default behavior, or at least configurable.
I realize there are ways to hack Gravity Forms into reordering things but it would be a great option.
There is a similar topic on this but it's closed and I'd really want to +1 the idea. :)
