You might have noticed in the November update of Desktop we added a new modeling view, that includes the ability to set ‘display folders’ for your fields! While it’s in preview, let us know your feedback, and look for it GAing soon!
Finally! This is a great improvement over not being able to group fields into folders at all. It will make a huge difference to the end user experience.
However, I'd really like to see it go much further - currently there doesn't seem to be the ability to nest folders inside other folders, there's no way to group tables into folders and there's no way to include fields from different tables in the same folder. This kind of functionality has been around for decades on platforms like BO and Cognos. It's still much better than it was though.
We have models with large numbers of tables and attributes - search helps but grouping in to folders would make things much easier for end users. Also the ability to order attributes other than alphabetically would be great.
I'm surprised this hasn't got more votes but good to see the status is "Started". I'm not sure how enterprise customers are managing without this feature to be honest.
