now, it'd be nice if this hack actually added new dialogue and other things to the game, but just the playable character is enough for me to be interested
Most people probably don't realise this, but this forum has had two editors for a number of years. One is the xenForo default editor, and the other is a custom editor I made years back I called BBCEd.
All the settings for which editor you use was lost during the upgrade. You can find the setting under Account Settings > Preferences > Editor.
