Make it possible to see full field name in Fields in Data Designer (whitespace)

I see that whitespace is a recurring topic among admins but I was unable to find a specific post for this.

To see a full name in a DD dataset, 9/10 times you have to hover over the field name, the names are truncated with ellipses despite the available space.
Definitely the use of space could be improved, even moving the group by to the right and decreasing the spacing among columns would make a big difference.
