I have been waiting for this feature. My last cable provider had the option, when you hit last, to see up to the last 8 stations you viewed. I really missed that.
It's great, say, for Saturday college football. I think it's great to see a list of multiple stations you watched. With this new feature I will be able to switch between multiple games. So, if I want to switch between 4-5 games I will be able to do that without having to search through the guide constantly. So for me personally, I love this new feature. My opinion. Great feature...
PS: And it's great that if you don't want the rail at times you have the option to disable it. Best of both.
Have a great day,
