With the Advanced Editor getting more and more Advanced, we've decided to give authors the ability to enable or disable portions of the editor. For now, the only feature you can change are Variables. As features are added, they may be included in different levels, so make sure to set your editor options to display those.
"As you become more comfortable with the Advanced Editor, you can change the features avaiable to you as an author. These options do not affect your storygame in any way; they merely show and hide different editing options. For example, if you create several variables and then disable the variables feature, the variables will still exist in the storygame but be uneditable by you.
In addition to this update, the STory Properties page has been rewritten; please post any issues you have with the Story Properties page.
