This simple plugin is a must-have for anyone that works with custom taxonomies or post types – and is an especially good compliment 
to Brad Williams’ indispensable <a href="https://wordpress.org/extend/plugins/custom-post-type-ui/" title="Custom Post Type UI" rel="ugc">Custom Post Type UI</a> plugin.
By default, WordPress only shows built-in taxonomies in your administrative list tables (e.g. Categories & Tags). But 
if you rely on custom taxonomies for organization (particularly when working with custom post types) then you are 
typically out of luck.
This plugin fixes that – ensuring that custom taxonomies are added as columns to all necessary list tables automatically.
This is an initial release and includes no bells or whistles – but if you need this functionality, you’re likely a developer 
just looking for a good head start, anyway. If you have any improvements, additions, or suggestions, please leave a post in the 
WordPress.org forums with the correct <code>custom-taxonomy-columns</code> tag.

Timeline Express – Single Column Add-On extends Timeline Express, and enables a new shortcode parameter <code>single-column</code>.
When set to 1 (eg: <code>[timeline-express single-column="1"]</code>), the timeline will display in a single column – similar to the default Timeline Express mobile view.
Basic Usage
If you want to set a timeline to single column you can add the ‘single-column’ parameter to the <code>[timeline-express]</code> shortcode and set it to <code>1</code>.
Example 
 [timeline-express single-column=”1″]

Timeline Express – Single Column Add-On
