At the old github page of ghostwriter http://wereturtle.github.io/ghostwriter/ ?? a couple of issues have been reported - most of them should still be valid. These issues should be transferred / imported into bugs.kde.org. At least the users should be informed about the status of the issues. Should open issues reported again in the KDE bug tracker? Thank you!
Closing this one because I no longer have the ability to reopen the GitHub issues. :( But don't worry, I've been fixing some of the most important ones that I remember off the top of my head. :)
