themeSwitcher Jul 04, 2012 / Updated: Jan 14, 2015
When this plugin is enabled, a selector will be visible at the upper left corner of the browser window. This enables a visitor to select which theme he wants to use.
Theme selection is stored in a cookie. The default duration of this cookie is 120 minutes, changeable by an option.
No theme participation is needed for this plugin. But to accomplish its independence the plugin will load a small css block in the theme head. The actual styling is an option to the plugin. A theme may replace this CSS via the themeSwitcher_css filter.
Themes and plugins may use the themeSwitcher_head and themeSwitcher_controllink filters to add (or remove) switcher controls. The active() method may be called to see if themeSwitcher will display the control links.
This extension is officially supported but not included in the ZenphotoCMS release.
