When I work with many data tables and only need one or a few enabled, with and a subset of the columns checked, it would be beneficial to collapse the data table structure with one click.
I find myself doing it manually most of the times.
So, one button next to the Show/Hide selection button to collapse/expand data tables structure
Yes, this is annoying. As workaround, type something in the search box which does not exist, like asdf and remove again. This will collapse all the tables...
I suggest to also have drag drop of filters in the dialog, and also to be able to select multiple filters and move them around.
