when you add a new linked record in interface designer, you have the option to toggle certain fields that you want to show up in a form if you don't want to actually open the record (helpful when you are adding multiple linked records like the products that a vendor has. It would be nice to resize the fields so I can pack more into the form without needing to scroll.
For example, if the cost of a product I'm adding is $5 I don't need a blank fillable space that is 3-4 inches wide across my screen. i could probably fit 2-3 more items in that same horizontal space.
