Earlier, I completed (in 30-45 min.) the task of making my "Grid" Tabular Layout from a 10-column-view into an 11-column-view profile, by simply adding the "Index" parameter, and having that assume Column 1, and then having the former 1st ten columns now assume Columns (2-11).
This submits my feature request of adding maybe, Excel/Outlook-style column reordering/sorting at the interface level, without having to call up the editor (the editor would reflect the changes in sort/reorder after the fact). This capability added into IMatch would have shortened the time to complete my above task vastly!
