For automatic navigation pls add the parameter auto_play=”true” in the carousel shortcode.
currently carousel shortcode doesn’t support sorting.
You can sort the post types by adding the parameter enable_sorting=true to the post snippets shortcode and then you will be able to sort the items using Post Type Reorder plugin.
[show_post_snippets post_type="course" number_of_columns=3 post_count=3 image_size='medium' excerpt_count=100 display_title="true" display_summary="true" show_excerpt="true" hide_thumbnail="false" enable_sorting=true]
If you have any further queries pls open a new topic.
