The new feature that keeps the guide views set to Favorites is convenient — one less button press.
However, one problem that now arises is that, if the current channel is not a favorite, then there's no information on it when you bring up the guide. To get it, you need to press the Favorites button to see the channel and then press it again to set the guide back to Favorites when you're done. So, maybe the current channel can be a temporary addition to the Favorites list.
And one more thing:
Actually, any channel that you enter can be a temporary addition to the Favorites list, for the duration of the session. You are entering it because you want to see that information. Again, you shouldn't have to press the Favorites button, enter the channel again to see it, and then press the Favorites button again to set the guide back to Favorites when you're done.
