/*FIXME: This is a place where Marc's idea for putting all the buttons and links and other widgets into an array is sorely needed instead of hard-coding everything.  Whomever implements that, PLEASE, PLEASE look at how the preview pane plugin code is used here to change some links and buttons and make sure your implementation can support it (tip: it may or may not be OK to let a plugin do the modification of the widgets, since a template set can turn on the needed plugin, but that might not be the most clear way to solve said issue).*/
