This tag will be used for refactor and updating of most of our preferences panels:
  This will include code changes that remove or condense old code
  This will include preferences being moved around to more logical locations
  This may include splitting up and/or condensing of tabs and/or subtabs for more logical placement of preferences
  This may include code changes that allow making changes to preferences faster and easier
  This will not include adding preferences
