Can you change the default item view count in magento?

[rosscope]

Hello all. I was wondering if it was possible to change the default 

"view ## per page" option in magento on the Sales > Orders page.

To clarify, what I mean is Magento defaults to only being able to view 20 products at one time, I am hoping for a way to change this permanently to the max option of 200 per page.

Thanks,

This could be done by rewriting the following class: https://github.com/OpenMage/magento-mirror/blob/magento-1.9/app/code/core/Mage/Adminhtml/Block/Sales... or copying it into the local code pool.

The only change that would need to be made is the addition of:

protected $_defaultLimit = 200;
