Con Doesn't directly manage plugins.
Other plugin managers will install, enable, and disable plugins for you. This one doesn't. If it's in the bundle directory, it gets loaded, if it's not, it doesn't. This can make it difficult to debug which plugin is causing some unexpected behaviour, as there is no simple way to enable/disable loading a plugin.
