Re: why would you make something harder to find rather than leaving it where it was in the main menu where it was very easy to access
Because the "main menu" may not be there at all - and the "main screen" may not be there at all anymore with the new option to hide the account list screen ("main screen") entirely.
And why did we add the option to hide the account list screen?
Because when you have just one or two accounts you don't really need it, it's just a lot easier to use if the app "launches into" a message list directly and exits when you tap Back there.
It is an option and it can be left disabled - but enabling it completely hides the "main screen" and "main menu" so we had to find a new home for Backup and Restore (and for "about" too, by the way).
