I installed, not sure what it does, site looks the same. site loaded fast already so maybe it will make a difference when there is more users or content.

I tested this plugin in elgg 2.3.2. The plugin works, I also noticed better performance for loading pages. But it prevents opening ajax pages of feedback and support.

This plugin is obsolete. There is no need to install this plugin on elgg 2.3.2. The lazy hover feature is part of core.

thank you
