LPS-38131 Usability bug - On a mobile device, it is difficult to navigate to a thread that is nested in subcategories 

Hey Nate. Out of all the panels that Juan suggested be closed by default for mobile - all but one already has defaultState=closed. That one comes from the calendar portlet, and the change will be in a separate pull request with the same LPS ticket number. Let me know if you feel like we can solve this problem any other way.
