It would be great not only to have Widgets to be published in the sidebar, but also the contents of custom_fields. If there was a predefined list of custom fields like eg.
and so on, one could display information related to articles or pages in the sidebar without having to hack around the source code or any knowledge of php (I have functions.php in my mind). Until now, I can only work with the widget_logic-plugin, but when you reach the 20-widgets-mark in primary aside, things start to look strange...
Good idea? Bad idea?
