I can't seem to figure out how to include all of the products that are saved into the Wish List show up on the Dashboard. It only shows 3 items, similar to the sidebar. Is there a way to fix this?
This is where you can adjust number of products for sidebar in the file app/code/core/Mage/Wishlist/Block/Customer/Sidebar.php:
protected function _prepareCollection($collection)
Just change setPageSize(3) to something else, or remove completely setCurPage(..) and setPageSize(...). That's how all those kind of constraints are applied.
