FlexGrid - Highlight Filter tab when filters are applied

Domenico Panetta

When there are filters applied to groups (either in Pivot or Flat mode) these are not displayed in the headers with the classic funnel icon:

We propose to highlight the Filter tab with a colour (or other ways) whenever a filter is applied to any field in the FlexGrid:

This would also be useful to have immediate evidence of filters on fields that can only be displayed using scrollbars.

Thank you
