At first glance, I wonder if this is more of a feature? We could simplify the app structure by just making a back button, and just keep them that much more simple. Even when there are hundreds of apps available for the Saint Maker, can't see the average user having more that 20-30, so clicking back to home and then selecting the next app they want to use won't be that big of a deal, it's just one more click. From a more theological perspective, I think that approach would also help people focus, using one app at a time, and when they are done, having to return home to choose the next one. Makes using an app an exercise in intention, and just the second it takes to go back home gives a little time to form the intention for your next move. Those are just my initial thoughts, I'll think about it some more.
