Wordpress Widgets - not just for the sidebar.
The files below are from my hacked version of widgets. It implements a render replacement of [[Widget Name]] with a call to that widget. This means widgets are freed from the sidebar and can be embedded into a posting.
- widgets/README.txt - needs updating
- widgets/widgets.php - see diff
- widgets/wpmu_widget_bindings.php - this maps [[]] names to functions
- widgets/mrjc_widgetize_function.php - this holds the bulk of my mods (see below).

I’ve mailed the wp team to ask if it can go in the distro.
