WP Plugin Manager lets you disable plugins on specific pages and posts so they only load where needed. No code required.

Manage which plugins load on what page with simple regular expression pattern matches similar to an Apache .htaccess file

Tracks plugin activity, including activation, deactivation, addition, deletion, and updates, with date, time, and user information recorded.

Create plugin collections and install them in one click on any WordPress site.

Central dashboard and module manager for compatible MAD CAT Design® WordPress extensions.

Displays the number of installed, activated, and deactivated plugins directly on your WordPress dashboard.

Move inactive plugins out of the plugins folder into an archive, then restore, download or permanently delete them later.

WordPress tells you which plugins are active. It never tells you which are used. PluginTidy works that out, and keeps working it out.
