Is it hard to make facebook your home screen for part of the time? That'd be pretty cool, hit a button to give your phone a huge facelift* as you walk out the office door each evening, or set it to switch automatically at 5pm and back at 9am.

*if you see what I did there.

It definitely would be possible by combining something like Tasker (https://play.google.com/store/apps/details?id=net.dinglisch....) with a custom application that swaps the home screen. Some of them automation apps support a scripting language too, so it might be possible without the custom app.

Sure, but the topic of the post is Facebook creating a home screen. If you find it inappropriate at work, then I guess you just don't use it at all, and you are not the target audience for the application.
