You can use Javascript to hide individual panes. Technically it's a bit of a hack so no guarantees it will continue to work forever, but if you want to hide the inventory for example you can put the following in a .js file:
$(function() {
var $inventoryLabel = $("#inventoryLabel");
var $inventory = $inventoryLabel.next();
$inventoryLabel.hide();
$inventory.hide();
});
That uses jQuery to hide the inventoryLabel and the element following it. You can find out the label names using the HTML Developer Tools in v5.3.
