Why not allow the sim to go directly to the Welcome page? Yup, get rid of the start key thingie!
Then if there is an update show on the Welcome page a message stating so, and a url to see the notes. And have a button to allow the Update to take place. Otherwise maybe we don’t really want to update yet because we just have to go flying right now. Also some people have slow download speeds so maybe they don’t feel like waiting for a long time. Just me two cents.
