Child Theme Wizard is a WordPress plugin by Jay Versluis that 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 fild 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 uplaoder for this feature.
