I have recently migrated a customer from NAV 2015 to Business Central and they are upset about the shrinking size of their dropdown lists.

For example, when selecting items in sales orders, purchase orders, etc:

On NAV 2015, the dropdown list is 9 columns wide and 7 rows deep

On BC, the dropdown list is 4 columns wide (at a stretch) and 5 rows deep

This is a HUGE usability problem, which forces the users to click "Select from Full List" nearly 100% of the time. I would like to see the dropdown lists either made bigger, and/or support height and width parameters.
