Whenever you have to pick one of your sub-accounts the "Chose sub-account" view is opened. At least on Android this view just shows a flat list of all your sub-accounts ordered by their creation date. Worse still, if you have multiple profiles (e.g. personal and business) then the sub-accounts of all profiles are merged into the same list (still ordered by creation date).

It would be immensely useful if this view sorted sub-accounts in the same order that they appear on the "Me" screen and grouped them by profile, just like on the "Me" screen. Would make it a lot easier to identity accounts if you have a few of them.
