Today many AOL/AOM forms have specific filter controls for only a few columns of the main form data grid. These controls take up space and don't give users a lot of flexibility. Analyzing the results of the usability study leads us to believe that users would respond well to having an Excel-like filter tool for each column in the grid. This control would replace most of the specific filters on grid-based forms such a "Tag Raw Data".
The attached mock-up shows a design for this filter.
