Hi

In this example:
http://dev.sencha.com/deploy/ext-4.0.2a/examples/grid/buffer-grid.html


I'd like to add a button titled "Read all", and when it is clicked, all rows should be loaded so no more buffering.

This is useful when the user wants to have more control over all the contents without having to wait for the buffer to finish in special cases.

Thanks, any help is appreciated
