Child Theme Wizard
A WordPress plugin that creates a new Child Theme with one click from the admin interface.
Once installed, head over to Tools - Child Theme Wizard. Pick a parent theme, fill in the relevant details (title, description, etc) and click Create Child Theme. Upon success you'll find you new Child Theme under Appearance - Themes.
You have the option to include GPL License Terms if you wish. The Wizard will automatically create a basic thumbnail too. In future versions I may include an image uplaoder for this feature.
