Child categories
If you use child categories in your posts’ organization you can now see them with padding on the left and a light arrow before each list. But note that categories imported through a widget don’t work as they should. In that case, child lists aren’t set with the correct markup and won’t be skinned correctly. To prevent this from happening you have to extract the categories’ block out of the widgets loop, as I did with the pages block (the blue one on top of your sidebar).
Corrections : you can use the standard widget for your categories, but you have to modify one line in /wp-content/plugins/widgets/widgets.php , on line 858 replace < ?php wp_list_cats("sort_column=name&optioncount=$c&hierarchical=$h"); ?> by a simple < ?php wp_list_cats(); ?> and child categories will be displayed correctly.
If you can or don’t want to edit this php file, just download it and overwrite it in your directory (/wp-content/plugins/widgets/)
