Have a countdown in the corner (or make it movable) when an app gets within 2 minutes of locking

I think it would be great to get more than a 5-minute heads-up that an app is about to lock to prevent starting a new game round or video and getting it cut off in the middle. For example, my Facebook app has 10 unlocks a day, but that lock always comes up in the middle of a video that I want to finish. So, I end up using another unlock and run into that problem again and again. It would be great to be able to see a count down (not a 5 minute notification) when there is 1-5 minutes left that is out of the way to avoid this.
