Like most folks, these changes are not improvements.  I suspect that the people that ok'ed the changes don't actually USE the store.

Quick question - Did you realize that you broke the customer's ability to check to see if any of their products were updated?

Example:  I check once a month to see if any products are updated.  Under the old system, I click on update, I would get every product that was updated - in order latest to newest.  With the reset, I now only get the updates PER PAGE!  I can only check 50 items at a time - why is that a problem? I own 2,335 items - which means I would have to scroll through 467 pages to see if I had any products updated.

With a store - functionality should be king, not eye candy.  This isn't rocket science.
