That’s a good thought. I hadn’t really thought about turning the excerpt off. I’ll add this to the possible features list.
At the moment you can manually modify the plugin. But keep in mind that any changes to the plugin file will be erased when you update the plugin to a new version down.
in the post-tiles.php file on line 571 remove the $temp_excerpt variable.
Current line 571:
$output .= "<li ".$featured_style." id='".$theID."'><a href='$temp_link' class='".$cat_var."' style='background-color: $cat_var_value; $featured_border'><h3>$temp_title </h3>$temp_excerpt</a></li>\n";
Updated line 571:
