If you take the time to read the review link that Shaun provided, you would see that there is a simple way to deal with the overnight problem. You just need to create an extra profile (looks like about 30 seconds work). This is described very nicely in the review. While I have not tried this app, if I did need the ability to switch profiles, I would start with this one. If it works as claimed (which it probably does based on the review), then this is the app everyone in this thread is looking for. 73
