Radio Buttons for Taxonomies vs WP Custom Menu Filter Plugin

Replace the default taxonomy boxes with a custom metabox that uses radio buttons… effectively limiting each post to a single term in that taxonomy. A plugin options page allows the user can select which taxonomies she’d like to switch to using the custom radio-button style metabox. Originally based on the the class by Stephen Harris Support Support is handled in the WordPress forums. Please note that support is limited and does not cover any custom implementation of the plugin. Before posting a question, read the FAQ and confirm that the problem still exists with a default theme and with all other plugins disabled. Please report any bugs, errors, warnings, code problems to Github

WP Custom Menu Filter Plugin uses a new filter hook in WordPress 3.1 that allows Custom Menus to be filtered. Instead of using the generic CSS {display:none;}, this plugin actually excludes nav menu items from even being created. While it uses the CSS class tag in the Custom Menu to determine which custom menu items should be excluded, it does not use CSS to hide the menu items, which savvy users can discover. Instead using one custom menu, the user can hide portions of their custom menu to visitors (even the savvy ones) while revealing other portions of their menu to users who are logged in and vice versa.
