@mrt_rl no it’s not working in Catch Everest v0.1.3. You need to patch the theme yourself as described in the first post (edit function catcheverest_post_sliders() in inc/catcheverest-functions.php), or better make a child theme for this patch, so it won’t be lost on theme update.
See http://codex.wordpress.org/Child_Themes on how to make a child theme. Copy this code into the functions.php of your child theme: http://pastebin.com/Bgy75VuG
BTW: This forum is really really crappy.
