This feature now affects either the slider or the story stacker.
Log into your website and visit Appearance / Theme Options / Featured Content
There you will find a field titled ‘Slider Speed‘. Change the value and experiment with the results!
If you enter a higher number the slider or story stacker will move slower. Want it faster? Enter a number lower than the default of 5.
This feature was in high-demand, so thanks for the feedback that led to it!
