Autofilter Functionality for Matrix
On Matrix and Table visuals, it would be useful to have Excel-like Autofilter functionality. Currently, the user can only sort columns in ascending or descending order. It would be useful to have Text and Number filters built into the header bar as well.
...also the drop down list to search for values within the column along w/ check boxes. Basically, the exact same functionality you have in Excel would be wonderful.
