//New Additions:
// - auto sidebar fix
// - document stats in the Tools menu
// - added ability to set insertion points in speech docs!
// - added ability to select a document as the current speech doc
//   (visual bug: if an open doc becomes a speech doc, or if an open speech doc becomes a regular doc, the send to speech / set insertion button
//                will have the wrong text but will work correctly)
