Description - The new filter experience does not close once a selection is made, like the legacy filters, views, and grouping do.
Why is this feature important to you - It's impractical for this box to stay open and to have to manually close it, when we are used to the better functionality that exists in the legacy experience.
How would you like the feature to work - Close after selection is made and for this to be fixed prior to Views and Grouping being rolled out.
