A separate sub-menu to organize the extensions belonging to parent plugins.

Generally, when we try to find plugin conflicts we have to deactivate every single plugin, including the extensions belonging to the parent plugins. If a site has 50 plugins including the extensions, it's impossible to differentiate the extensions as well. Because the extensions are mixed inside the plugins sections as well. So a separate sub-menu should be added to keep track of all the extensions, belonging to the parent plugin. Since WordPress is getting bigger, I assume this feature is very important to every plugins and extension organized.
