CTMod works by having a central core mod into which other mods can be added and removed, similar to web browser plug-ins. A user may have as many or as few components of CTMod beyond the main one installed as they like. Installing a component is as simple as loading the addon containing it, and uninstalling simply means not loading the addon anymore. Components automatically register their options and control buttons with the main CTMod interface, thus keeping all controls for CTMod in one central location.
