Is it on the list to add a rownumberer column type? Its not difficult to create the effect by adding a gridcolumn and specifying a renderer which does what Ext.grid.RowNumberer does but it will be great to have a grid column with xtype:rownumberer in the toolbox.
I tried creating a custom tool but the designer refused to import it (other column types would import successfully). My guess is that the designer application has not required Ext.grid.RowNumberer so under the covers the application is failing to handle the xtype.
