 - `Plugins/CogAI` - ImGui windows for AI (Behavior Tree, Blackboard)
 - `Plugins/CogInput` - ImGui windows for the Enhanced Input library (Input action, Gamepad)
 - `Plugins/Cog` - The main Cog plugin which contains the following modules
-  - `CogEngine` - ImGui windows for the core unreal engine functionalities (Log, Stats, Time, Collisions, Skeleton, ...)
-  - `CogWindow` - ImGui window management (Base Window, Layout)
-  - `CogDebug` - Debug functionalities (Log, Debug Draw, Plot, Metric, ...)
-  - `CogImGui` - Integration of Imgui for Unreal, inspired by [UnrealImGui](https://github.com/segross/UnrealImGui)
+  - `Cog` - Cog Subsystem (Manage windows, menu, settings, layout, ...)
   - `CogCommon` - Interfaces implemented by your project actor classes which cannot be excluded from a shipping build
+  - `CogDebug` - Debug functionalities (Log, Debug Draw, Plot, Metric, ...)
+  - `CogEngine` - ImGui windows for the core unreal engine functionalities (Log, Stats, Time, Collisions, Skeleton, ...)
+  - `CogImGui` - Cog own integration of Imgui for Unreal, inspired by [UnrealImGui](https://github.com/segross/UnrealImGui)
 - `Plugins/CogAll` - Only contains a utility function to easily add all the built-in windows from all the Cog plugins. Useful for projects that do not need to exclude some plugins. 
 - `Plugins/CogCommonUI` - Contains an implementation of CommonUIActionRouterBase to let the Cog shorcuts work while in a CommonUI menu. Only use this plugin if you use CommonUI.
