This plugin adds shortcode handling to the widget_text filter so that shortcodes can be used in Text widgets on the sidebar.
Want to use shortcodes in your sidebar Text widgets? Don't want to have to update the functions.php of the theme to achieve this? WidgetShortcodes comes to the rescue. This plugin simply hooks shortcode_noautop and do_shortcode to the widget_text filter to make this happen. It keeps on working even if you change themes.
There are no setup options in this version. It is turned on by activating the plugin and turned off by deactivating it. Easy, peasy!
