+* WM client lib that implements afb calls to the WM

+X Application structure, whereas controller events should be forwarded to it?
+  Decorator? Proxy?
+X Loose coupling between API calls and the actual handler in the appliation,
+  perhaps convert the verb's json input into a nlohmann::json and pass it to
+  some app method which then in turn can return a Result<error, json> kind
+  of thing. The verb's entry point would then construct a reply accordingly
+X Design a sensible and lightweight representation of a Layout inside the WM
+  Appication.
+* Wm Objects (Layers, Screen, Surface, Areas?) Should be handled with IDs, only
+  Upon making the concrete calls shall the actual objects be resolved.
+* Implement an application configuration, possibly in /etc, must contain:
+  - json configuration names
