Empty Filter Spot for Hidden Fields

Loooooove this app - so amazing. As a newbie developer (background as an admin) this was so easy to get set-up on.

Currently when you set it so a field is not a filter option, it leaves a blank space - this can be a weird user experience. Would be awesome that there were not any blank filter spots if a field/column is set to not be a filter option.
