There are many different types of totals..
row subtotal, column subtotal, row grandtotal, column grandtotal, grand grandtotal
Also only some members (but not all ) may be selected in the filters.
The context we get by clicking on All member row or column should be clear and accurate.
Many times we need not show subtotal rows and columns. We should be able to hide All rows/columns.
It would be better if the kendo pivotgrid is enhanced with these requirements in mind.
