You’re not stupid! You’re smart and samboll’s comment must refer to a different version of Mystique than either you or I have. I am using v1.72. At least for Mystique 1.72 there is no such:
Admin > Settings > Featured Content Gallery
and there are also no “duration options” at:
Admin > Appearance > Mystique settings > Posts
although there is a setting there for “Maxiumum number of featured posts”. If there is a timing duration setting, I can’t find it either. Maybe the theme designer removed the timing option (and I vaguely remember one in a prior version).
This theme is in active development, so stuff comes and goes with every version, and other stuff radically changes. None of this is documented very well, either, so for now you really have to be careful when upgrading this theme, especially if you have made modifications to either your UserCSS or to any of the php files. I’m sure the documentation will solidify when the theme development gets closer to completion.
