What does it happen? This plugin creates a new menu option in new/edit post. A second option to select categories in new post option. Well, the problem is: When you install this plugin, it overwrites all you selected in the default category list/select of WordPress, when you're writing a new post. So, if you think you selected the categories in default wordpress category box/menu (that's is easier cause you can type the category name and it searches and shows only the categories that begin or include the word you typed) but nothings is shown when you publish. When you submit the new post, if you dont use the box of categories of this plugin (theres is no differect if you hide id in options/show menu), the result is that all you've checked in default category menu/box of wordpress are overwritten by "no-category" option. Its a conflict beetween the default menu/box category and the new menu/box category created by this plugin in admin new/edit post. (post.php) So it erases the post categories Ive selected and publishes with "no-category" option. Even if you edit the post and try again to select the right categories in default box/menu of category list, it overwrites again. So. Youre mandatory have to use the menu/box of this plugin, that in my case, is worse than the default wordpress menu/box category. So I had to delete this plugin.

Does exactly what it says on the tin. Simple to use and install. Bug free. Would be great to be able to use this functionality in pages and posts via a shortcode.

Useful tool adds simple functionality to the Wordpress Categories widget. Would be nice if there was an option to have tabs automatically collapse for each new page. But works good right out of the box, does exactly what it says.
