Yeah, I've kinda left the Action stuff a little hazy for now. I wanted to get feedback on the general menu definition/configuration approach before spending too long working out how all of the actions will fit in, both here and elsewhere in the project.
You made some good points about the async nature of many of the action results, Richard, which I failed to take into account. I shall have a think about how we can factor that in to this makeup.
