This is a December 2015 fix of the eminently useful WME Panel Swap script by JJohnston84, idea by ottonomy. A recent WME change altered the name of a property and broke the script. SAR85 identified the issue and gave me the fix. JJohnston84 has not responded to contact attempts yet, so I'm uploading here for distribution to Waze editors.
Because I'm posting it, Greasyfork is crediting me as author, but I certainly did NOT write this.
