just a quick question. – i currently use register_sidebar_widget to include my plugins in the dynamic sidebar. – unfortunately it is not possible to add a description for the widget with this function.
if you have a look in the widgets.php, you can see that in contrast to the recommendations in the api, the included widgets by automatic implement wp_register_sidebar_widget instead and thus also have a description.
which function do you use? do you think that wp_register_sidebar_widget will be changed in the (near) future or can it be used without re-coding on every wp update?
