A handy WordPress plugin for batch creation of taxonomy terms in your preferred hierarchy. 
Indispensable tool for WordPress developers.
<h3>Getting Started</h3>
After installing and activating the plugin, go to Tools -> Quick Term Creator. Please, refer to the Usage section below for usage information and examples.
<h3>Usage</h3>
When you go to Tools -> Quick Term Creator, you will find a form that allows you to bulk insert taxonomy terms. The form contains the following fields:
Hierarchy Indent Character
Specifies the character (or set of characters) that are used to specify the hierarchy indentation. You can use those characters in your Terms text, prepending one or more terms with one or more of these characters. You can read more about how this field is used in the “Terms” field description below.
Taxonomy
Specifies the taxonomy of the terms that you want to bulk create.
Terms
Allows you to insert as many titles of terms as you wish. Each term should be on a separate line. You can additionally prepend each term with one or more hierarchy indent characters. For example, if your character is an asterisk – <code>*</code>, you can use one asterisk at the beginning of an term to specify that it is a child of the last item without any asterisks. You can use 2 asterisks at the beginning of an term to specify that it is a child of the last item with 1 asterisk, and so on. There is no limit of how deep you can go with your hierarchy. Also, there is no limit of the number of terms that you might want to bulk create.
<h3>Examples</h3>
Example 1
The following example will create 5 category terms with the corresponding titles.
<ul>
<li>Hierarchy Indent Character: <code>*</code></li>
<li>Term Type: <code>Category</code></li>
<li>
Terms:
Term 1 
Term 2 
Term 3 
Term 4 
Term 5
</li>
</ul>
Example 2
The following example will create 5 category terms with the corresponding titles and the specified hierarchy (X1, X2 as a child of X, X1a as a child of X1 and X2, X and Y as parents).
<ul>
<li>Hierarchy Indent Character: <code>-</code></li>
<li>Term Type: <code>Category</code></li>
<li>
Terms:
Term X
<ul>
<li>Term X1 
— Term X1a</li>
<li>Term X2 
Term Y</li>
</ul>

The Child Theme Wizard lets you create a new child theme without the need for additional tools, right from within the WordPress admin interface. Once activated you can find it under Tools – Child Theme Wizard.
Specify a parent theme, customise options such as title and description and click Create Child Theme. Upon success you will find your new theme under Appearance – Themes.
You have the option to include GPL License Terms if you wish. The Wizard will automatically create a thumbnail too. In future versions I may include an image uploader for this feature.

Child Theme Wizard

I actually installed another plugin before this one. I wanted to check theme overrides on a VPS (Dreamhost) install. This worked, the other plugin did not!

It was simple to use, although if a link to the page to generate could be placed on the plugin listing page, that'd be fantastic.

One other minor comment, is that I feel all themes should be lower-case and it generated an uppercase folder... wp-content/themes/Twenty-Twenty-Child

Really every theme should have this built-in, it's a great utility and saves a lot of boilerplate generation.

Great plugin, did what I wanted

Creates a child theme with one click and lets you customise its options.
