Voting starts in March for the Drupal Association Board election.
This module replaces the add node by nid function from Panels with an add node by uuid functunallity. You'll be able to select the node as usual but instead of catching the nid, this module will catch the uuid of the node and safe it in your pane.
Now it is possible to export a panel with nodes in it (if you import the nodes with uuid).
With uuid_features it should be possible to add the nodes in the same feature as the panel, wich would be a nice way to get dummy content installed with your feature.
