From the plugin admin screen you can create rules by specifying a key word or phrase along with an existing 
WordPress category. Th plugin then scans post titles for the key, and adds the specified categories as appropriate. 
By default the plugin will automatically check newly created posts when a page is loaded, however this can be set to manual via a button in the admin screen.
I can’t guarantee any support, but if you use the support forum I will do my best to help you with any issues. 
Feel free to suggest improvements too.

Smart Categories

This simple plugin adds categories to posts based on key words or phrases in the title.

Multi-Column Taxonomy List is a plugin that allows you to list your categories, tags, or custom taxonomies into multiple columns.
This plugin is great to use on custom archives index pages to display all categories, tags, and custom taxonomies on a single page. You can also turn the list into links to the RSS feeds for your taxonomies.
<h3>Usage</h3>
<h4>Shortcode attributes</h4>
You can implement a new list by adding the shortcode <code>[mctl]</code> to the content of a page. By default, it will output the categories into three columns with a heading of Categories. You can customize the output using attributes in the following format: <code>[mctl taxonomy='post_tag' title='Tags']</code>

<h4>Template tag</h4>
Alternatively, you can implement a new list by adding the the template tag <code><?php multi_column_tax_list(); ?></code> anywhere in the code of your theme. Just like the shortcode, by default it will output the categories into three columns with a heading of Categories. You can customize the output using a string of parameters in the following format: <code><?php multi_column_tax_list( 'taxonomy=post_tag&title=Tags' ); ?></code>
Refer to the above attributes for customizations.
