 *  The editor should support (maybe as extension) versioning.
 *  This doesn't have to be git or svn but at least multiple version should be able to get stored into the database.
 *  The versioning should be very straight forward and only contain a version number, date and optionally a version name.
 *  The basic save button should be just "save new version" or something similar.
 *  Based on this it should also be possible to compare different versions against each other.
 *  It should be possible to see who wrote which word, when and what it got changed to (e.g. git or microsoft track change mode).
