Maybe I am just approaching the way the forms work now wrong. As far as form sections, I only have 3, just different layout sizes 1, 2, and 3 columns. Not really sure what else we would do with those. The thing we miss the most are the layouts and alternate layouts. This is where we added javascript and things. Then the alternate layouts were nice for having fields and versions of the form that we only wanted to show in the admin area.
I would love to see an example of what others are doing with them.
The macros are not the end of the world, we were able to easily pull fields from the user that we pulled from AD. Things like employee number or department number that the user may not know off hand. I'm sure we can find work arounds, was just nice how easy it was before.
