Nice work, I like the approach. Did you inspire your work in how Dolphin and VAST implements menu creation, command execution, and so on? I find your solution similar to how Dolphin implements it, where even each Presenter is even queried about each command by using a command query and routing solution.
Will you use this in the context of Calypso and friends? Regards! Esteban A.
