New Grid component and inline editing

Hi,

I really like the way new Grid component is getting its shape and I love the idea to support editing data
by double clicking a row where user at the end has a choice either to accept the changes or discard them.

I did a very simple example with it and am calling:

grid.setEditorEnabled(true);

I would like however to be able to customize the area where “Save” and “Cancel” buttons are located.
Eg I would like to make this area bigger and put there some additional controls including labels and
RichTextArea components.

Is it something that could be fairly easy done using the new Grid component ?
Or I am doomed and have to do my own coding using some kind of popup component ?

Thanks,
Adrian
