Provide the ability for the developer to configure the grid so that the Group By box appears _below_ the CommandItem

I spend too much time hunting through the design time settings looking for a property settings. For example, your documentation indicates that I can produce a message to ask a user to confirm a row deletion when they click on a Delete button by adding some text to the ConfirmText property of the GridButtonColumn.  Where the heck is this?  I wish you would provide a "Search for this property or method" in you design control so that I could easily find the setting.   Same suggestion goes for all of your complex controls.  Thanks!
