You could ask one of your data analysts to run a query finding all users who have at least one table with more than 20 columns. I am sure that all these customers would be happy to have column groupings. This would measure the value of this feature.
I would like to also vote for this feature. Having table with 50 columns. When editing a particular record (expand record), I’d like to see fields grouped. Otherwise it is an explosion of fields very inconvenient to maintain.
I do have separate views...
