The account settings certainly aren't in the wrong place. As in GNOME, you set up the account once in the system settings and you can use it with all applications without having to set it up again and again if you want to use different applications. I think it kiiind of 'works' like this in Android now, too. Of course, with Jolla still restricting third party access to any and everything, this isn't very obvious, but it is the intention. I hope we will live to see the day the restrictions are lifted.
