Would be useful to unlock pane on checkout page. Sometimes it useful to make possibility to remove it from checkout and show it other way (pop-up window by click on special link). Below is code.

function commerce_userpoints_discount_commerce_checkout_pane_info() {
   $checkout_panes['commerce_userpoints_discount'] = array(
     'title' => t('!Points discount', userpoints_translation()),
     'page' => 'checkout',
-    'locked' => TRUE,
+    'locked' => FALSE,
     'file' => 'includes/commerce_userpoints_discount.checkout_pane.inc',
     'base' => 'commerce_userpoints_discount_pane',
     'weight' => 10,
