There is a set of Modules, that can be installed/uninstalled from Lordui. Modules are being managed by the Programs Author and only the Author my expose new Module on official Lordui Module Server. However there is always possibility of creating own, custom module. The aim of separating out Modules from Lordui is to enable turning off the Lordui's functionality, that may be not needed for big group of users.
You can manage modules in Module Manager. Module Manager is available under Menu 'Help' -> 'Modules'. You can browse, install or uninstall modules from the server or local file. By default, the official Lordui Modules Server is used, however you can change that using settings under button.
To install the module select it on the modules list on the left side and hit Install button on the top side. You can update all the modules, that have the update available on the server, using 'Update modules' button on the bottom side.
