I'm yet to spend time on this, just wanted to let you know that I absolutely despise those walking tour flying dialogs. They're very annoying and quickly move my eyes from the dashboard (what I want to see) to something I couldn't care less about.
If you dismiss them, they don't reappear do they? They shouldn't at least...
Do you think it would be better to infer from one tour dismissal that a user never wants to see another tour for anything else?
