This is part of the azurecurve ClassicPress Plugins which introduces the plugins I have available for ClassicPress.
The plugin I am going to cover in this post, is an existing one which has been brought up to coding standards; Theme Switcher.
Theme Switcher allows users to switch between different themes using the supplied widget; example uses would be to allow them to change mode between light and dark themes.
This site uses Theme Switcher to allow users to Change Mode between light and dark; you can try this using the Change Mode widget in the sidebar.
The plugin can be downloaded via my Development site.
